New: Sig P320 Grip Module from Mirzon

The Sig Sauer P320 is perhaps the most popular full-sized handgun from the gun maker. It’s been on the market since 2014, and in almost a decade of use it’s not only maintained but gained widespread use. Considering how many competition shooters and self-defense gun owners use the Sig P320 regularly, it comes as no surprise there are also a lot of aftermarket options available for it. Now there’s one more, a new grip module, coming from Mirzon.

The new grip module from Mirzon is made from polymer and has numerous features designed to increase the shooter’s comfort while improving accuracy. Forward, angled slide serrations provide an indexing reference, and a lower beavertail facilitates a more secure, while still suitably high, grip. This enhances control and accuracy. Uniquely designed finger channels are subtle enough to fit a wide variety of hand sizes and serve to make the module ergonomically correct and comfortable.

From Mirzon regarding their new grip module:

“The all-new P320 XCARRY composite grip module by Mirzon provides enhanced comfort for better overall control. The low beavertail helps reduce recoil and mitigates muzzle-flip while overmolded rubber panels with slightly raised finger channels provide for comfort and a sure grip.”
