Sig Sauer P365 vs P320 – Which Is Worth Buying?

Sig Sauer Duel: P320 vs P365

We were looking for the most popular concealed carry handguns in the market and came across the Sig Sauer P-365 micro-compact pistol and P-320 subcompact pistol. While we’ve heard that both are reliable, we wanted to see for ourselves how they compare. We’re not partial to one model, but we just wanted to test which is better out on the range.

The differences between Sig 365 pistol and the P320 sub-compact pistol are their versatility and capacity. With the interchangeable frame sizes of the P-320, you don’t need to purchase three separate guns. You can purchase one subcompact model and quickly change to a compact or full size version. Still, given the 6.7 overall length, it’s slightly taller than the P-365, and even the small Glock gun.

On the other hand, the Sig Sauer P-365 pistol only comes in a micro-compact model that’s great as a concealed carry. Despite its size, you can utilize a 10rd standard mag compared to the usual 6-7rd capacity of other similar-size guns.

Design & Ergonomics

With slimmer width, full textured grip frame, and aggressive slide serrations of the P-365, we found the gun comfortable. It also features a stainless steel slide and Nitron slide finish.

Overall, since you may interchange P-320’s grip, frame, and calibers, this gun gets the best advantage when you carry a gun. Change from full size to compact quickly. P-320 and P-365 also have an integrated accessory rail, though the frame rail of the Sig Sauer P320 sub-compact is a proprietary frame rail.

Size & Weight

Well, in terms of size and weight, the P-365 pistol gets the full market advantage. It has an overall length of 5.85in, a height of 4.3in, and a barrel length of 3.1in. Compare that to the 6.7in overall length, 4.7in height, and 3.6in barrel length of P-320. Meanwhile, Sig Sauer P365 weights 17.8 oz while P320 is at 24.9oz. Regardless, both aren’t full-size guns, so their build makes them popular for concealed carry.

Ammunition

As mentioned, you can swap out the ammunition calibers of the Sig Sauer P320 sub-compact, including the .40 S&W and the 9mm. Meanwhile, P-365 is rated for +P 9mm ammo. Based on research, most users find the guns unfaltering with any ammo type, including modern JHP.

Trigger​

You can expect a smooth and clean, crisp trigger pull on both guns whenever you shoot. You should note that at approximately 7lb, P-320’s pull is a little heavier than the 6lb pull of P-365 pistol.

Safety

sig p365 safety

P-320 and P-365 features a striker safety, disconnect safety, and magazine disconnect safety.

In essence, the manufacturer claims the pistols won’t fire unless you want them to.

But regarding external security, P-365 pistol models also have optional manual ambidextrous safeties available.

Sights

P-365 comes with high contrast, X-Ray3 day/night sights, making a rapid target acquisition possible even under low lighting conditions. P-320 also offers night sights (SIGLITE), but some prefer the contrast sight option. As for the sight radius, the P-320 pistol is a little longer at 5.5 inches next to the 4.9 inches of P-365.

P365 vs P320 Sub-compact Rounds

When it’s time to test the pistols, we ran over 500 rounds, and both performed flawlessly.

It’s only because of the higher round capacity that we prefer the P-365 better.

The double stack 10 rd mag of P-365 is already at its best, but the 12 and 15 rd extended magazine are great additions, especially in the 9mm market.

Accuracy

Overall, if you’re new to the trigger of both guns, your shooting accuracy may be affected. But generally, we found the pistols to be pretty accurate from the short 7, 10, and 15 yards to the extended 25 yards. Still, like other guns, you’ll need practice if you want to get a tight group on your target.

When it comes to P320 sub-compact or P-365, our final verdict declares the P-365 pistol as the winner. It may be one of the best 9mm in the market today, considering its size, ergo, capacity, and accuracy. Given its high round load despite its micro-compact design, you might find it a good gun for concealed carry, especially when paired with a great holster.

If your duty would often require you to change pistols from full size to a subcompact, the versatility of P-365 is your best shot. Besides the easy and quick changing of the grip modules and frames, you could really save a lot from your purchase.
