Sig P365 SAS is a lightweight, powerful pistol that has been designed to provide the versatility of both 9x19mm and .380 ACP calibers in one package. We’ve been waiting a long time to do this Sig P365 SAS Review. The Sig Sauer P365 offers the ballistic advantage of the larger cartridge with reduced recoil, allowing for faster follow-up shots. Featuring a compact frame size (6+1 or 7+1) and 12 and 15 round capacity, the P365 is an ideal everyday carry pistol.

With a clean, crisp trigger pull and consistent trigger feel, the P365 SAS offers outstanding shootability with either cartridge. The ergonomic slide stop lever makes it easier to release the slide and return to the battery, so there’s no need to take your hand off the grip. A diminutive micro-compact design makes this striker-fired pistol easy to carry all day long, while at the same time providing unprecedented 10+1 full-size capacity.

Features of Sig P365 SAS

Safety Mechanism

A safety mechanism is a mechanical device that blocks the operation of a firearm as long as it is not deactivated or disengaged, usually by the action of the trigger. The Sig P365 SAS includes an automatic firing pin safety and a striker blocker, which prevents the firing pin from moving without engaging the trigger first. Also featured is trigger safety, which only allows the trigger to be pressed when it is fully depressed. The laws regarding safety mechanisms vary greatly by country, and may often be ignored during work (such as the military), but are generally required to be used in competitions by organizations such as IPSC. It is also the law in many municipalities for a gun to only have one active safety mechanism.

Sig P365 SAS Safety Mechnism


The sights on the Sig P365 SAS are the centerpiece of the gun’s accuracy and utility, as they allow you to quickly line up your shot whether you’re using one-handed or supported shooting positions. Everyday carry pistols are often equipped with both front and rear sights, which provide aid to aligning your shots before you take them. They allow you to quickly get on target for multiple shots at the desired point of impact.  Front sights are normally placed on the muzzle end of the barrel near the junction with the slide.  However, front sights can also be mounted onto the slide itself. Sights come in many different configurations and types, such as fixed iron sights or flip-up designs that are located on top of the slide.


These allow an increase in accuracy when firing by allowing for finer target discrimination and elevation adjustment. However, front sights can sometimes interfere with the use of a mounted light. You might notice that there is no railed muzzle on the Sig Sauer P365 SAS, which means you cannot attach a laser or flash to it without some DIY modifications. The solution is to buy aftermarket sights such as Truglo TFX Pro Series Handgun Sight Set designed specifically for the Sig P365. This allows you to mount a laser or tactical light onto your firearm, allowing you to more accurately engage targets in low-light conditions.

Trigger Mechanism

The trigger mechanism in a firearm is the mechanical part that controls the release of the stored-up potential energy. It fires a cartridge, using the explosive in the cartridge to propel a projectile forwards from the gun. The trigger itself does not fire any ammunition, but simply activates or releases other mechanisms which do so. Trigger pull refers to how much force must be used to pull the trigger and fire around. You can adjust this by adjusting the tension or weight of the trigger itself, which varies from firearm to firearm.


In most handguns, there is an external safety mechanism that will prevent it from firing unless you fully depress the trigger. This may be combined with a spring-loaded firing pin which gives a “hair trigger” effect, meaning it needs only a very light pressure to activate.  In general, the lighter it is, the more likely you are to accidentally fire your weapon when you don’t want to, though some shooters prefer this for tactical reasons.

The magwell on the Sig P365 SAS is designed to provide a larger and easier insertion point for your magazine, which speeds up the reloading of the pistol. Typically featured on competition pistols, adding a magwell or funnel can greatly increase reload speed by allowing you to position your hand closer to the base of the magazine while performing tactical reloads. Tactical magazines often have a flared base plate, so the funnel shape is designed to pull the magazine into position rather than pushing it. This increases your consistency while shooting and allows you to perform tactical reloads in case of an emergency or malfunction.

Aesthetics refers to the set of principles that guide artistic endeavors. The aesthetics of Sig Sauer P365 SAS is sleek and modern-looking, while also being durable and functional enough for everyday use in the real world. The Sig Sauer P365 SAS has a full-size frame with an overall length of 7.2 inches but is only 0.94 inches thick. The grip width measures 1.0 inches, giving you ample surface area to hold onto the weapon even when you are wearing gloves or have larger hands. The Sig Sauer P365 SAS has an extremely low profile due to its small size and shape.


The center of gravity is also low, which makes it easier to control and fire compared to other handguns with a similar caliber. This means you won’t have as much trouble controlling the weapon when firing or taking multiple shots at close-range targets. The overall weight of the Sig Sauer P365 SAS, including the additional extended 12-round magazine, is just under 21 ounces. This makes it easy to carry around and keep with you at all times without weighing you down too much. The lightweight also serves as an advantage when firing the weapon, making recoil less of a problem.

Grip refers to how you hold the firearm when you are aiming and firing it. Your grip must be firm enough to keep the weapon steady, but not too tight that you limit blood flow to the shooter’s hands. There should also be a balance between how much pressure is being applied by the fingers on top of the grip and by the palm. This is also called the “crack of your knuckles” and you can find it by opening your hand flat with your fingers together and touching the tip of each finger to the pad on the opposite side. The Sig Sauer P365 SAS has a unique grip design, which is found in many handguns made by Sig Sauer.


The front strap is actually made from a special polymer material that reduces the risk of it getting caught on the draw when you are trying to quickly pull your gun out of its holster. In addition, this polymer also makes up the entire grip frame itself and even the magazine. The checkering pattern found on both sides of the grip gives your hands extra traction and lessens the chances of it slipping out from underneath your fingers. There are no sharp edges or uncomfortable spots on the grip, which further enhances comfort and reduces the risk of injury.

Mag Release

The mag release is generally located on the side of the firearm, though some have them placed at different places according to what is most comfortable for you or accessible with your shooting hand. This is especially important if you are left-handed. The mag release is the mechanism on the firearm which physically locks or releases the magazine. To lock, find it on your Sig Sauer P365 SAS and press inwards, to unlock push it outwards until you hear a click.


This ensures the magazine stays securely in place. You can use your mag release to make reloading quick and easy, as you don’t need to break your shooting position or take the eyes off of a target. If you do not have a round in the chamber, simply hit your mag release and remove the magazine with your support hand (you should practice this while pointing in a safe direction), then insert a fresh magazine and release the slide to load your firearm.

Slide Lock

The Slide Lock is the button located at the rear of your Sig Sauer P365 SAS, specifically on its left-hand side. Pressing this button will hold the slide open, after the last round in your magazine has been fired or when your Sig Sauer P365 SAS is empty. This will allow you to get rid of the old magazine and insert a new one, before releasing the slide lock which will then chamber the round in place.


An aftermarket part is a part that has been designed and produced to replace an original equipment manufacturer (OEM) component of a vehicle or other manufactured product. OEM parts are the parts originally used by the automobile manufacturer in its assembly, which generally benefit from economies of scale in production, engineering design, and testing. The aftermarket consists both of parts manufactured by companies other than the OEM, as well as modified or improved versions of parts made by the original manufacturer.

Advantages of Sig P365 SAS


The Sig Sauer P365 SAS is lightweight and small enough to fit inside a pocket. This makes it easy to carry and be prepared for the worst-case scenario, as well as allowing you more freedom of movement while carrying concealed.


There are many aftermarket accessories that you can attach to your firearm, enabling you to tailor it to your specific comfort, needs, and preferences.


The Sig Sauer P365 SAS features manual safety, which is the simplest form of firearm action that protects against accidental discharge. It is an external device consisting of an object that obstructs the path of the hammer or striker to prevent it from striking the firing pin unless actuated by the trigger.


Since the Sig Sauer P365 SAS is semi-automatic, it will fire one round with each pull of the trigger. If you don’t pull the trigger and all your rounds have not been fired yet, there is no need to worry as this firearm’s magazine has mechanical safety.

Disdvantages of Sig P365 SAS


The Sig Sauer P365 SAS is incredibly loud. It can cause hearing damage without protection.

Since there are many different models of Sig Sauer P365 SAS, some have reported that certain parts break or stop working, causing their Sig Sauer P365 SAS to stop functioning properly.

Reliability Issues
