Features Comparison: SIG P320 vs SIG P365
1. Size and Concealability
SIG P320
The P320’s size, on the larger side of compact, provides a solid grip. During my testing, its 7.2-inch overall length and 1.4-inch width felt substantial in hand, offering stability and confidence during rapid firing.
This size makes it a bit more challenging to conceal, especially for those with a smaller frame or preferring deep concealment.
SIG P365
The P365, on the other hand, shines in concealability. It’s remarkably compact, with a length of just 5.8 inches and a slim 1-inch width.
During my field tests, it slipped effortlessly into various concealed carry positions, from IWB holsters to ankle rigs, without compromising comfort or drawing attention.
Winner
When it comes to size and concealability, the P365 takes the lead. Compared to the P320, its smaller frame makes it a more discreet choice for everyday carry without sacrificing ergonomics or handling.
2. Ergonomics and Handling
SIG P320
The P320’s larger frame offers a more robust grip. This was evident in my field tests, where rapid target reacquisition was more manageable due to its stability.
The interchangeable grips add to its ergonomic versatility, accommodating different hand sizes comfortably.
SIG P365
The P365’s ergonomics are impressive for its size. Despite its smaller frame, it doesn’t feel cramped.
During testing, it offered a surprisingly comfortable grip and manageable recoil, though the smaller size meant a slightly less stable hold compared to larger models.
Winner
In terms of ergonomics and handling, the P320 edges out. Its larger size and customizable grip options provide a more secure and adaptable handling experience, especially under rapid-fire conditions, compared to the smaller P365.
3. Sight Radius and Accuracy
SIG P320
The P320, with its longer sight radius of 5.8 inches, allows for more precise aiming. This was evident in my accuracy tests, where hitting distant targets was more consistent.
The SIGLITE night sights also provide excellent visibility in low-light conditions.
SIG P365
The P365, while having a shorter sight radius, still offers commendable accuracy for its size. The XRAY3 Day/Night Sights are clear and easy to align.
In my testing, it performed admirably at close to medium ranges, though the shorter sight radius was a factor at longer distances.
Winner
For sight radius and accuracy, the P320 stands out. Its longer sight radius, compared to the P365, allows for more precise shot placement, particularly at greater distances.
The quality of the SIGLITE night sights also contributes to its superior accuracy in various lighting conditions.
4. Trigger Feel and Response
SIG P320
The P320’s trigger offers a smooth, consistent pull with a clean break. During my field tests, I appreciated its predictability, which contributed to accurate shot placement.
Its weight range of 5.5 – 7.5 lbs strikes a good balance, providing enough resistance for control while remaining responsive.
SIG P365
The P365’s trigger, with an approximate 6 lb pull, is remarkably crisp for a gun of its size. It offers a tactile reset, which I found advantageous for quick follow-up shots.
The trigger’s performance is impressive, especially considering the compact nature of the firearm.
Winner
While both triggers are excellent, the P320 edges out slightly with its slightly wider range of pull weight and consistent feel, providing a slightly more refined shooting experience compared to the P365.
