SIG’s P320 has a serialized, internal frame that can be easily removed from the polymer grip frame and dropped into…well…there aren’t as many options as one might hope. Considering the pistol’s popularity, its adoption by the military, and its modularity I believe we’ll continue to see the aftermarket step in and make grips, accessories, and even complete conversion systems for the P320. New to the market is Mirzon and their Enhanced Grip Module:
For $159, the Mirzon grip frame replaces the factory SIG unit with an extremely ergonomic, beavertail-equipped grip. It accepts the factory controls and is available for manual safety-equipped and sans-safety models.
Rubber inserts provide grip and comfort on the front- and back-strap. A little ledge under the pinky finger area helps control the firearm’s flip and torque under recoil.
Without a doubt, the grip is extraordinarily comfortable. It feels great. Back-to-back with a factory P320 grip it’s a definite improvement — I feel like my hand encompasses more of it, with better angles and more traction, and that I would have more control over the firearm. The polymer appears to be high-quality and the molding is clean, though the overmolded rubber isn’t perfectly aligned on all of these show frames.
We’ll see if we can’t [literally] get our hands on one for a full test rundown soon.
