Since moving from New York to Texas I have purchased and sold numerous handguns. I get a fair amount of range time and I get to know each, from time to time I provide my reviews to Serpent Tactical LLC. I’m fairly certain that SIG offers the most robust lineup of handguns on the market. I have several SIGs in 9x19mm, but the P320 left a decent impression on me.
Like many manufacturers, SIG is responding to Glock’s dominance of the striker fired handgun market. The development of a modular striker fired handgun is essential as SIG (among others) look to cut away at Glock’s market share by offering improved ergonomics and accuracy off the shelf.
The P320 is the cousin of the P250, as an alternative it offers a modernized polymer frame with a striker fired action. My initial impression was positive, I really appreciate the overall feel and weight as the heft is indicative of quality. There are two major differences from between the P250 and the P320, the addition of slide serrations on the P320 and the adoption of a striker versus Double Action Only (DAO) operation. Visually they are very much alike.
The P320 is a complete line of handguns and it’s a truly modular concept, unlike the handguns made by SIGs competitors. The P320 utilizes the same trigger group for every handgun frame of the line, be it 9x19mm Luger, .357 Sig, .40 S&W, however the .45 ACP uses a slightly larger element. There are four polymer grips options, three slides, and numerous barrels. Moreover the slide and frame combinations allow for versatility for the shooter. Because the P320 line offers four handgun sizes that serve four chambering configurations, those who invest in the several chambering and grip options for the P320 will find many of handgun requirements all in one model.
Design and Features
The P320 has a truly elegant profile, modern attractions without features that go as far as to be considered a futuristic look. A well designed and machined stainless steel slide with contouring and a frame that covers the essentials, offers medium-grade ergonomics, and the stippling on the grip is a departure from SIG’s typical panel style grips featured on their DA/SA handguns.
The slide serration improvement on the P320 was a step in the right direction. Gripping the slide to either put a round in battery or to pull the slide to the rear is an essential task of operating any handgun, industry standard pretty much mandates front and rear serrations, the P320 nails this simply and effectively.
The P320s trigger is decent, it is very much the same trigger featured in the P250 with a pull of 5.5-6.5lbs. The P320 does not have a match-grade trigger option, such as SIG’s popular Short Reset Trigger (SRT). The SRT option on SIG handguns increases the crispness of the trigger and reduces take-up, since the trigger on the P320 feels slightly gritty, it may benefit from some refinement or the SRT option in the future. To put it plainly, the trigger on the P320 is not the best among all the handguns I’ve owned. I would be go as far as to say that unless you are in a speed competition I don’t really think SRT matters much as handguns intended for a duty or carry environment may want to avoid reduced trigger pull as a safety consideration.
Disassembly and Maintenance
Disassembly of the P320 is very simple if you’ve ever owned or handled a SIG, it keeps with tradition and follows the same format. Lock the slide and manipulate the takedown lever, then release the slide. Simply remove the recoil spring and barrel and the P320 is ready for maintenance. Unlike the Glock handgun design, there is no need to pull the trigger when disassembling.
Like any SIG I’ve shot, accuracy is not an issue with the P320. Quality materials and craftsmanship lend to a solid product, the P320 is designed to perform. Like any handgun, familiarization, comfort, muscle memory, and range time are what provide for proficiency. I typically shoot at 7-25 meters for handgun in order to maintain proficiency. While shooting the P320 I noticed that I need a 6 o’clock hold on my target, however it may be the range I’m shooting at. Naturally, at a slow rate of fire my groups tighten up, and faster rate of fire opened up by 2.5-3.0 inches at 25 meters.
The P320 joins the growing ranks of modular polymer handguns that are essentially forming a coalition known as the anti-Glock. The P320 keeps within the same price point as Glock, but you won’t get the high end feel that you’ll find in the HK lineup of VP9 and VP40. What you’ll gain as an alternative to Glock is a lifetime warranty offered by SIG, and certainly improved ergonomics. The modularity offers a spectrum of options, from home defense, concealed carry, or range shooting. The P320 is an incredibly reliable handgun, the handgun you would trust your life with.
