Welcome to our comprehensive Sig P365 review. The Sig P365 has revolutionized the world of CCWs with its innovative design and exceptional performance. This small pistol offers a high capacity in a compact size, making it an ideal choice for daily carry.

In this review, we’ll explore various aspects of the Sig P365, including its aftermarket magazines, magwell, and more, to provide a thorough understanding of why this gun has become a favorite among enthusiasts and professionals alike.

Aftermarket Magazines

One of the standout features of the Sig P365 is the availability of aftermarket magazines, which enhance the gun’s versatility and performance. Sig Sauer offers a variety of magazines, including 10, 12, and 15-round options.

These high-capacity magazines allow users to tailor their concealed carry setup to their specific needs. For instance, the 12-round magazine includes a pinky extension, providing a good grip for those with larger hands while maintaining the gun’s compact profile.

The extended magazine options also feature magazine base plates that improve the overall ergonomics of the grip module, offering more control during shooting.

Aftermarket options from other manufacturers include even more enhancements, such as improved magazine release mechanisms and extended magazine base plates that allow for quicker reloads.

For left-handed shooters, these aftermarket magazines and mag releases can be particularly beneficial, providing more customization to ensure a seamless and comfortable shooting experience.


Magwell p365

The magwell of the Sig P365 is thoughtfully designed to facilitate fast and efficient magazine changes, a crucial feature in high-stress situations. The magwell’s beveled edges guide the magazine into place, reducing the chances of fumbling during reloads. This is particularly important for a small firearm intended for concealed carry, where every second counts.

For those looking to optimize their shooting experience further, aftermarket magwell enhancements are available. These can include flared magwells that expand the opening, making it even easier to insert a magazine quickly. This is especially useful during competitive shooting or tactical training where rapid reloading can make a significant difference.

The magwell also plays a critical role in the overall ergonomics of the Sig P365. A well-designed magwell ensures that the extended magazine fits seamlessly, providing a secure and comfortable grip without adding unnecessary bulk. This balance is essential for maintaining the small pistol’s concealability while enhancing its functionality.


Grip Ergonomics p365


From my personal experience, the grip of the Sig P365 is one of its most remarkable features. Despite being a small handgun designed for concealed carry, the Sig P365 manages to provide a grip that feels surprisingly full and secure.

The design of the grip module plays a significant role here, as it is contoured to fit comfortably in the hand, ensuring a solid hold even under rapid-fire conditions.

When I first picked up the Sig P365, I was immediately impressed by how naturally it fit into my hand. The grip length is sufficient to allow most shooters to get a full grip, with the standard magazine providing a secure hold for the pinky finger.

For those with larger hands, the extended magazine base plate on the 12-round and 15-round magazines offers additional room, ensuring a good grip without compromising the gun’s compact nature.

The grip also complements the overall ergonomics of the handgun, making it easy to reach and operate the mag release and slide stop without having to adjust my grip. This intuitive design is particularly beneficial during high-stress situations, where efficiency and speed are crucial.

Additionally, as a left-handed shooter, I found the ambidextrous features of the Sig P365 to be a welcome addition, allowing for seamless operation regardless of hand dominance.


The texturing on the Sig P365 is another aspect where this handgun truly shines. The grip texture is aggressive enough to provide a secure hold, but not so rough that it becomes uncomfortable during extended shooting sessions. This balance is essential for a daily carry firearm, where comfort and reliability must coexist.

In my shooting experience, the texturing offered excellent control over the gun, even when my hands were sweaty or wet. The front and back straps feature a stippled pattern that enhances the grip without being overly abrasive, ensuring that my grip remains firm throughout the trigger pull.

This secure hold contributes significantly to the gun’s overall accuracy, as it minimizes movement and allows for precise shot placement.

The texturing also extends to the takedown lever area, ensuring that all parts of the grip are easy to handle. Whether you’re performing a quick reload or engaging in double-action shooting, the consistent grip provided by the texturing instills confidence and control.

This consistency is a key factor in achieving a good sight picture and maintaining accuracy, especially in dynamic shooting scenarios.

In this Sig P365 review, it’s clear that the grip and texturing are designed with the shooter in mind. The thoughtful design elements contribute to the gun’s reputation for being extremely accurate and comfortable to shoot.

Whether you’re engaging the front sight for a precise shot or manipulating the striker-fired mechanism, the Sig P365 offers an ergonomic and reliable experience that stands out in the world of concealed carry handguns.

Sig P365 Sights

When discussing the Sig P365, it’s impossible to overlook the quality of the sights, as they are a crucial component of the shooting experience. In this Sig P365 review, I’ll share my personal experiences and insights on the sights, highlighting their effectiveness and usability.

One of the standout features of the Sig P365 is its stock X-RAY3 Day/Night sights. These sights are incredibly versatile, providing excellent visibility in both bright daylight and low-light conditions.

The front sight is equipped with a high-visibility green dot, which contrasts sharply against the blacked-out rear sight. This design ensures a clear and quick sight picture, allowing for rapid target acquisition.

From the moment I first aimed with the Sig P365, I was impressed by how quickly and naturally my eyes were drawn to the front sight. This is particularly important in a self-defense scenario, where every fraction of a second counts. The bright green dot on the front sight is easy to pick up, even in stressful situations, ensuring that my shots are on target.

The rear sight is equally well-designed, with two tritium inserts that glow in the dark. This makes the Sig P365 an excellent choice for nighttime or low-light shooting. The combination of the front and rear sights provides a balanced and intuitive aiming system that enhances accuracy and confidence.

Whether I’m shooting at the range or in a defensive situation, the sights on the Sig P365 give me the assurance that I can place my shots precisely where I want them.

In my experience, the sights also contribute to managing recoil effectively. The clear sight picture allows me to maintain focus on the target, even during rapid fire. This is crucial for a striker-fired pistol like the Sig P365, where quick follow-up shots can be necessary.

The reduced muzzle flip and controlled recoil help keep the front sight aligned, enhancing overall shooting accuracy.

Another aspect I appreciate is how the sights integrate seamlessly with the gun’s overall design. The grip module, slide stop, magazine release, and takedown lever are all ergonomically placed, allowing for a smooth and intuitive shooting experience.

For someone with medium-sized hands like mine, the Sig P365 offers a comfortable and secure grip, ensuring that the sights remain steady and aligned during shooting.

For left-handed shooters, the ambidextrous features of the Sig P365, including the reversible magazine release, are a significant advantage. This makes it easy to operate the gun and engage the sights regardless of hand dominance.

The sights are designed to be effective for all shooters, contributing to the Sig P365’s reputation as a versatile and user-friendly pistol.

The sights on the Sig P365 are a key component that enhances its performance and usability. They provide a clear and quick sight picture, are highly effective in various lighting conditions, and integrate well with the gun’s overall design.

Whether you’re engaging in double-action shooting or rapid fire, the sights on the Sig P365 ensure that you can shoot accurately and confidently. This new Sig is truly a standout in the realm of concealed carry pistols, offering features that cater to both new and experienced shooters alike.

Controls Sig P365


In my experience with the Sig P365, I found the approach to safeties to be both user-friendly and practical. The model I use does not have a manual safety, which simplifies the operation and reduces the likelihood of forgetting to disengage a safety in a high-stress situation.

This design choice aligns with the philosophy of many modern CCW, emphasizing simplicity and readiness.

For those who prefer an additional layer of security, Sig offers a version of the P365 with a manual thumb safety. Positioned for easy access with the thumb of your firing hand, it is designed to be intuitive to engage and disengage without disrupting your grip or shooting rhythm.

Personally, I find the absence of a manual safety on my model to be advantageous, as it reduces the steps required to make the firearm ready to shoot.

The P365 also includes internal safeties, such as a striker safety and a disconnect safety, ensuring the gun will not fire unless the trigger is deliberately pulled. This enhances the overall safety of carrying the P365 without compromising its readiness for defensive use.

Magazine Release

Magazine Release p365

The magazine release on the Sig P365 is another well-thought-out feature that enhances its usability. Positioned in a standard location just behind the trigger guard, the mag release button is easy to access without needing to shift your grip significantly.

This placement allows for quick and efficient magazine changes, which is crucial in a defensive scenario.

As a left-handed shooter, I appreciate that the magazine release is reversible. This adaptability makes the P365 a versatile choice for both right- and left-handed users. The release itself is responsive, providing a positive click when pressed, ensuring the magazine drops free smoothly.

During my time shooting the P365, I found that the mag release worked flawlessly with both the standard 10-round and the extended 12-round and 15-round magazines.

Slide Stop

Slide Stop p365

The slide stop on the Sig P365 is designed to be low profile, minimizing the risk of accidental engagement while shooting. Despite its small size, the slide stop is easy to operate when needed.

Positioned on the left side of the frame, it can be released with the thumb of the shooting hand, or for left-handed shooters like myself, with the index finger of the support hand.

I found the slide stop to be particularly user-friendly when performing reloads. After inserting a new magazine, a simple upward swipe with my thumb or trigger finger quickly sent the slide forward, chambering a new round. The slide stop’s design strikes a good balance between being unobtrusive during shooting and easily accessible when necessary.

The slide itself moves smoothly and consistently, contributing to the overall reliability of the firearm. In the time I’ve spent with the P365, I haven’t encountered any reliability issues related to the slide stop or the slide mechanism. The gun’s compact frame and well-designed controls ensure that it remains easy to handle, even under rapid fire.

In comparison to other popular CCW options like the Glock series, the controls on the Sig P365 feel more refined and ergonomically positioned. This contributes to a more intuitive and enjoyable shooting experience, whether I’m at the range practicing or relying on the P365 for everyday carry.

The controls on the Sig P365 are thoughtfully designed to enhance the shooter’s experience. The safeties provide peace of mind without complicating operation, the magazine release is responsive and adaptable for left-handed shooters, and the slide stop is both unobtrusive and functional.

These elements, combined with the gun’s good trigger and overall reliability, make the Sig P365 a standout choice for a concealed carry firearm. Whether you’re carrying for self-defense or simply enjoying a day at the range, the Sig P365 offers reliable performance and ease of use in a small, powerful package.

Overall Ergonomics

Draw Speed

When it comes to concealed carry, overall ergonomics and draw speed are critical factors, and the Sig P365 excels in both areas. From my personal experience, the ergonomic design of this firearm enhances its usability and effectiveness, making it a top choice for everyday carry.

One of the first things I noticed about the Sig P365 was how naturally it fit into my hand. The grip is designed to provide a secure hold without feeling bulky, which is crucial for a small-size weapon intended for concealment.

The grip module’s contours and texture offer just the right amount of traction, giving me confidence that the gun won’t slip, even if my hands are sweaty or wet. This design requires only a little more grip than usual to maintain control, especially during rapid shooting.

The Sig P365’s ergonomics extend to its controls, all of which are intuitively placed. The trigger, slide stop, and magazine release are easily accessible without needing to shift my grip, which is essential for maintaining a consistent and quick draw.

As a left-handed shooter, I appreciate that the magazine release is reversible, making it just as convenient for left-hand operation. This ambidextrous feature ensures that the P365 is versatile and user-friendly for all shooters.

Draw speed is a critical component of defensive shooting, and the P365 does not disappoint. The gun’s small size makes it easy to conceal in various holster options, whether inside-the-waistband (IWB) or outside-the-waistband (OWB). The smooth contours of the P365 ensure that it doesn’t snag on clothing during the draw, allowing for a quick and fluid motion.

During my practice sessions, I found that I could consistently achieve a rapid and smooth draw from concealment. The ergonomic grip and intuitive control placement mean that as soon as I clear the holster, the P365 is ready to shoot. The trigger, known for its good pull, has minimal take-up and breaks cleanly, which is vital for accurate first shots.

When comparing the P365 to other popular CCW, such as those from the Glock lineup, I found the Sig P365 to be more comfortable to draw and shoot. The compact design and thoughtful ergonomics of the P365 gave me an edge in both speed and accuracy.

The gun’s design minimizes the need for adjustments during the draw, which can save precious seconds in a defensive scenario.

Another factor contributing to the P365’s draw speed is the placement and design of the slide stop. The low-profile, easily accessible slide stop allows for quick reloading.

After inserting a new magazine, a simple swipe of the slide stop sends the slide forward to chamber a round, ensuring the gun is ready to fire with minimal delay. This efficiency is crucial when seconds count.

In terms of reliability, I have experienced no issues with the Sig P365. The gun has functioned flawlessly with various types of ammo, including both standard and +P loads. This reliability, combined with its ergonomic design, makes the P365 a dependable choice for anyone looking for a small caliber weapon for self-defense.

The option to add a red dot sight further enhances the P365’s capabilities. A red dot sight can improve target acquisition and accuracy, especially in high-stress situations. The P365’s design accommodates this accessory without compromising its concealability or draw speed.

In conclusion, the overall ergonomics and draw speed of the Sig P365 are standout features that enhance its appeal as a concealed carry firearm. The gun’s thoughtful design, comfortable grip, and intuitive controls make it a joy to shoot and carry.

Whether you’re a left-handed shooter or prefer a small, reliable gun for everyday carry, the Sig P365 delivers a performance that instils confidence and ensures readiness in any situation.

Sig P365 Maintenance

Sig P365 Maintenance

When it comes to maintenance, the Sig P365 stands out as a user-friendly firearm. Regular maintenance is crucial to keep any gun in optimal working condition, and the P365 makes this task straightforward and efficient.

As someone who shoots frequently and relies on my firearm for daily carry, I’ve come to appreciate the ease of maintaining the P365.

The P365 comes with clear and concise instructions in the box, which most people will find helpful. The disassembly process is simple, requiring no special tools. First, ensure the gun is unloaded by checking the chamber and removing any magazines.

Then, lock the slide back using the slide stop. The takedown lever, located on the left side of the frame, is easy to manipulate, even for those with smaller hands. Rotate the lever downward, release the slide, and it will come off the frame effortlessly.

Once disassembled, cleaning the barrel and other components is a breeze. The small size of the P365 means fewer nooks and crannies compared to larger guns, making it easier to reach all the parts that need cleaning.

I typically use a standard gun cleaning kit with solvent and oil, which works perfectly for the P365. After a thorough cleaning, reassembling the P365 is just as straightforward: slide the barrel and recoil spring back into place, align the slide with the frame, and rotate the takedown lever back to its original position.

In my experience, regular maintenance has prevented any reliability issues. Despite putting hundreds of rounds through the P365, I haven’t encountered any malfunctions. This reliability is especially important for a CCW, where you need to trust that the gun will function flawlessly if needed.

Comparing it to other popular models like the Glock 43 or Smith & Wesson M&P Shield, the P365’s maintenance process feels more refined and user-friendly. The P365’s components fit together seamlessly, which I believe contributes to its overall reliability and ease of maintenance.


In terms of aesthetics, the Sig P365 is a sleek and modern firearm that stands out on the market. From the moment I unboxed my new Sig, I was impressed by its appearance. The design is clean and streamlined, with no unnecessary frills.

This gives the P365 a professional and serious look, appropriate for a defensive weapon.

The P365’s black nitron finish on the slide not only adds to its visual appeal but also provides a durable, corrosion-resistant surface. This is particularly important for a daily carry gun, which is supposed to withstand various environmental conditions.

The finish has held up well against wear and tear, maintaining its sleek look even after extensive use.

One thing I particularly like about the P365 is its compact yet robust appearance. Despite its small size and lightweight, it looks and feels substantial in hand. The grip texture and the overall ergonomics contribute to its aesthetic appeal, making it look capable and ready for action.

For someone with small hands, like myself, the P365 doesn’t feel too bulky or awkward, which can be a concern with some other firearms on the market.

The P365 also features well-designed controls that blend functionality with aesthetics. The slide stop, magazine release, and takedown lever are all positioned ergonomically without disrupting the gun’s clean lines.

The slightly flared magwell and the beveled edges of the slide enhance both the appearance and functionality, making quick reloads easier.

When placed on the table next to other similar guns, such as the Glock 43 and Smith & Wesson M&P Shield, the Sig P365 often garners more attention due to its refined look. Its aesthetics are not just about looks; they also suggest the careful engineering and thoughtful design that went into its creation.

In my opinion, the Sig P365 hits the perfect balance between form and function. It’s a visually appealing firearm that also performs exceptionally well, which is exactly what I expect from a high-quality CCW.

Whether you’re new to carrying or an experienced shooter, the P365 offers an attractive and reliable option that stands out in both looks and performance.

Overall, the aesthetics and ease of maintenance of the Sig P365 enhance its appeal, making it a top choice for anyone looking for a dependable and good-looking CCW.

Shooting the SIG P365

Shooting At Distance

Shooting the Sig P365 is a pleasant surprise, especially considering its compact size. When I first took it to the range, I was eager to see how it performed compared to other full-size and compact pistols I had shot before.

The weight and balance of the P365 make it feel very stable in the hand, even when fully loaded with a magazine.

One thing that immediately stood out was the trigger. The trigger pull is smooth with a clean break and a crisp reset, which significantly aids in accuracy. I found that I could get back on target quickly, which is essential for defensive shooting scenarios.

The P365’s good trigger makes a noticeable difference, especially when shooting at various distances.

Shooting at close range, say 7 to 10 yards, the P365 is incredibly accurate. The sights align naturally, and the point of aim is easy to maintain. As I moved the targets further back to 15 and 20 yards, I was pleasantly surprised by how well the P365 held its accuracy.

Despite its small size, it performed nearly as well as some of the full-size pistols I’ve used, like my Glock 17. The consistent trigger and clear sight picture made hitting targets at these distances straightforward.

For example, during a recent shooting class, we practiced shooting at distances up to 25 yards. While I initially had reservations about the P365’s capabilities at this range, it proved to be more than capable.

The striker-fired design and ergonomic grip allowed for steady control and precise shooting. Most people might not expect a compact pistol to perform so well at longer distances, but the P365 consistently hit the mark, with tight groupings that I was proud of.

The recoil management is another aspect worth mentioning. Despite its lighter weight, the P365 handles recoil efficiently. The design of the grip and the low bore axis help minimize muzzle flip, allowing me to keep the front sight on target for faster follow-up shots.

This is particularly beneficial when shooting multiple rounds in quick succession, as the gun stays relatively steady in my palm.

In terms of capacity, the P365 offers an impressive 10+1 or 12+1 rounds, depending on the magazine used, which is more than adequate for most defensive situations. Having this capacity in such a compact firearm without significantly increasing the weight or size is a significant advantage.

It means I can carry more ammo without feeling the burden of a larger, heavier gun.

SIG P365 Review Conclusion

In conclusion, the Sig P365 is an outstanding option for anyone in the market for a concealed carry firearm. It offers a blend of compact size, high capacity, and excellent shooting performance that is hard to beat. The P365’s ergonomics, good trigger, and reliable controls make it a top contender in the category of everyday carry guns.

From personal experience, I can say that the Sig P365 lives up to the hype. It performs well at both close and longer ranges, making it a versatile choice for various shooting scenarios.
