Unlike any other pistol in its class, the P320 features a unique 5-point safety system, standard on all models:
The unique modular design of the P320 offers the user the ultimate in flexibility to change calibers, sizes, and fit. Small, medium, and large complete polymer grip modules ensure comfortable and optimal fit for the widest range of hand sizes.
I love my Sig P320 it shoots accurately feels good in my hand. I shot hundreds of rounds not one problem or jam & easy to clean. SOSS has great prices and excellent service, this is my second gun from them and will be more to come.
I am dying to see the final military version of the P320, but I am more than happy with this version already. Night sights, a nicer trigger, frames I can swap out for $50 or $60 to better fit my hands, and did I mention the nicer trigger? It's worth mentioning twice. The Glock is the Bic lighter of pistols. If you need fire from your pocket, use a Bic; if you need firepower from your pocket use a Glock. Neither one is anything super special, they are just the best functioning tools at doing their respective jobs within a certain price range. The Sig P320 is special. Interchangeable back straps PLEASE! Try the Sig whole frame & grip swap, and feel the difference. I have smaller hands, and put E2 Elite grips on my rare Sig P228R SRT Navy trials gun, made in Germany. Sig got it right with the P320. I put a medium frame on and it works; small is also nice. It has nice ergonomics, regardless of the frame size. FN's submission was also awesome. Glock was entering a 20th century gun in a 21st century contest and lost - BIG TIME! Pick the Sig P320 and I think you will agree, it is a winner. I am not particularly fond of striker fired poly guns, or most poly framed guns, but I really do like the P320 family of guns. The P250 hammer fired was not one that I cared much for. These almost have me sold on the striker fired poly frame. I don't complain about carrying one, and I don't worry about it not working. They shoot straight, they shoot nice, the trigger is much better than stock Glock. You get night sights with this model, and swapping grip sizes is fairly cheap, plus you can change whole calibers, or go to a full size, sub compact, or carry frame, and it's so EASY to do it.
Stripping Sigs has always been super easy. The P320 also did much better on snowmobile, and horseback patrols in snow, mud and ice than the Glock ever did. They tend to not jam up with mud and ice as much at all. I only wish Sig made a 10mm P320. I may try reaming out a .40, and see if it works. Everything on these is easy to work on. That is just Sig. 9mm, .40S&W, .357 Sig, and .45 ACP, and they can all work from the same fire control mechanism. That is quite a feat, and it's not that hard to swap it out.
The bad: The bore axis is a tad high, no 10mm, and that's about it. I don't notice it that much, but I have had the P228R tucked under my left arm for 10 years now. This will probably replace my rare German P228R SRT night sight Navy submission model. Like all Sigs, everything is well made, smooth, crisp, and feels super nice. It also has a nice rail, and is ready to accessorize. Bottom line - I will trust it to work when I need it to. I pray that day never comes again. If it does, I have all the confidence the P320 will work just as intended. I am also confident I will put rounds on target too. No guessing or hoping with this one. Practice a little, and you too will have a gun that builds and inspires confidence as a viable reliable defense tool.
