Size and Weight

The Sig P365 is a micro-compact pistol in contrast to the P320, which is a full-sized pistol. The overall length of the small P365 is 5.85 inches, while P320 stands at 6.7 inches. The considerable difference between the size impacts the weight of the pistol, with Sig P365 weighing 17.8 oz and P320 weighing 29.4 oz.

This also makes Sig P365 ideal for concealed carrying. The gun is also more suitable for extended use. P320, which is heavier, has more capacity, and so is perfect as a primary service pistol.

Magazine Capacity

There is not much difference in the magazine capacity of the two pistols. Sig P320, chambered in 9 mm, features a 17-round magazine capacity. Moreover, it comes with an optional 21-round extended magazine also.

Besides the 9 mm Luger, this large handgun can also be adapted to fire larger calibers. These include .357 SIG, .40 S&W, and .45 ACP.

The Sig P365 has a double-stack magazine whose capacity ranges from 10+1, 12+1, 15+1, and 17+1. You can bump it up to 21+1 full-size capacity.

The maximum capacity and capability of these guns make them ideal for combat, home defense, and everyday carry. Both will serve you well in case you are in a situation that demands rapid fires.

Sights and Optics

Both the Sig P365 and P320 come with Romeo reflex sights installed. The optic of this Electro-Optics brand of Sig Sauer is installed into a specifically cut low-mount dovetail of Sig P320. This exclusive slide-mounted optic ensures faster sight acquisition on your target. It also improves your accuracy. The handgun also has the SIGLITE night sights installed.

The P320 also has a Picatinny rail for mounting a light, laser, or training device, which is not the case with Sig P365. It has a proprietary rail that is compatible with certain accessories.

The Sig P365 has the factory ROMEOZero Elite micro red dot sight installed. The nitron slide of the pistol also has an XRAY3 Day or Night Front Sight. It is fully compatible with the Sig P 365XL rear sight assembly. These optics-ready guns allow you to customize your shooting experience according to your needs and achieve better accuracy.

Trigger and Action

Both the guns feature a striker-fired trigger system with a crisp and predictable pull. The difference lies in the heaviness of the trigger. Typically, the Sig P320's trigger has a higher pull weight than the Sig P365. It can lead to a deliberate trigger press, suitable for target shooting or duty use for some.

The trigger pull of the Sig P365 is lighter than the P320. Its break and reset mechanism is also more crisper than the Sig P320. It makes P365 ideal for precision shooting. The lighter trigger pull also works toward improving the accuracy of the pistol.

If you want to replace the stock trigger in your gun, you can explore the Sig Sauer flat trigger kit. The flat design is meant to provide shooters with a lower position on the trigger. In turn, this increases your leverage for a smooth and highly consistent pull.

Shooting Accuracy

When comparing Sig P320 vs P365 on the accuracy, we find no big differences. The P365 is an acceptably accurate micro-compact pistol with a lightweight trigger and decent sights. You can maintain considerable accuracy at normal distances of 10, 15, and 20 feet.

Besides the trigger, the high accuracy with P365 is majorly due to grip shape and texture, which leads to a tight and complete grip. The grip enables you to shoot single-handedly, but the tighter your grip is on the pistol, the more accurate your shots will be, and you will feel less recoil. It will also keep you on your target.

The full-sized Sig P320 boasts great shooting accuracy. It has been proven to deliver accurate results in 2,000 round tests, with no significant degradation from start to finish. The bigger size and heavier weight of the gun lower the felt recoil. The low recoil impulse facilitates a stable shooting platform, which makes quick follow-up or rapid-fire shots from different distances accurate.

Another noteworthy point is that when holding the P320, your hand rides high on the metal frame with an aluminum receiver. This shifts the frame to a lower bore axis. It, along with the pistol's design for an excellent hand fit, facilitates exceptional accuracy.

Sig P320 Vs P365 Ergonomics

Sig P320 Vs. P365

Sig P320 and P365 are ergonomically pleasing guns for many similar and different reasons.

Both the pistols are built on the tradition of modularity with custom FCU or Fire Control Units. It functions as the 'guts' of these handguns, according to Sig Sauer, so any shooter of any size and experience can modify the gun based on their body size, intended use, and even carry method. You can change the grip module so it fits your hands and achieves improved on-target accuracy.

The updated lightweight trigger in P320, reversible magazine release, substantial grip, and sandpaper-like rough texture make the gun highly ergonomic.

With regards to the Sig P365, it has a slim profile, crisp trigger pull, reversible magazine release, and comfortable grip despite the small size, which contributes to its ergonomics.

If you are looking for a compact and comfortable gun for everyday use, the P365 will be the ideal choice. However, if you need a bigger gun for duty use or home defense and you have larger hands, the Sig P320 will be a good option.

Sig P320 Vs P365 - Final Words

Besides size and capacity differences, there are no stark dissimilarities between the Sig P320 and P365. The difference in size and weight impacts the grip and handling of the guns. It also makes the Sig P365 more suitable for reliable concealed carry in an IWB (inside-the-waistband) holster than the P320.

The Sig P320 is an immensely accurate and soft-shooting full-sized pistol ideal for larger hands. You can carry it comfortably in an OWB (outside-the-waistband) holster all day long.

Moreover, if the size feels too much, you can make it compact or subcompact using the built-in FCU. The use of FCU is more advantageous for the P320 than P365. However, the P365 functions as a comfortable and high-capacity handgun that is most optimized for concealability. Make sure to test the pistols yourself before deciding on the ideal one.
