Wilson Combat WCP320 SIG P320 Polymer Frame

by Chris Mudgett

Superior ergonomics in under a minute

For long-time P320 shooters, the increased grip traction and ability to mitigate muzzle rise will be immediately apparent after swapping out your OE grip frame for the WCP320. At $64.95, it’s likely the best bang-for-your-buck upgrade for the P320 platform.

Since its 2014 debut, SIG Sauer’s P320-series pistol has been rapidly gaining steam, rolling over its competition in both the civilian shooting, competition and law enforcement markets; severely disrupting, or dare we say turning on its head, a market seemingly satisfied with the then-status quo service pistol availability. If that weren’t enough, it was adopted by the U.S. Military as its official sidearm—a crowning achievement solidifying the P320’s place as king of the polymer-framed, striker-fired pistols. If you don’t see it now, it will be clear in a few short years when the aftermarket finally catches up to the sweeping popularity of the pistol, overtaking the pistol that rhymes with “lock.”

Thanks to the P320s drop-in trigger module, even blindfolded, with one broken hand and a splitting headache, swapping out the grip module of your P320 should not take you any more than 60-seconds … no tools necessary. WCP320 grip module’s come 100-percent complete, with a factory-SIG magazine release button pre-installed.

If we sound like fan boys—well, we kind of are, with a few exceptions. Overall, SIG Sauer has done an outstanding job with the base P320. It is reliable, has a great trigger and is completely modular, allowing the user to go from a sub-compact all the way to a long-slide competition pistol—and everything in between—in under a minute, without tools. We love that virtually all components can also be exchanged with customized parts to suit unique tastes. We’re particularly thankful that the grip modules can be swapped out, because the current ones from SIG kinda suck, except the XCompact module, which was finally done right. Speaking of done right, that brings us to Wilson Combat, which rarely does anything wrong.

Bill Wilson is used to fixing other manufacturers half-assed attempts at making pistols and components, and has done the same here . . . in spades. Wilson and his team also identified that the P320’s shortfall was the ergonomics of the factory grip module(s) and set off to reengineer the frame so it would complement the rest the platform. After the smoke cleared, Wilson had created an optimized frame that checks all the boxes. The WCP320 offers significant improvements in shape, texture and overall ergonomics. The frame will make your P320 feel like an expertly sculpted custom gun, all thanks to a simple grip change.

Due to the P320s removable fire control unit, the pistol has a higher than average bore axis, which results in slightly more muzzle flip than some of its competition. The WCP320

With the top edge of the frames lined up with each other, it’s easy to see the high-cut 1911-style beavertail and undercut/radiused trigger guard of the WCP320 grip module, as compared to the factory SIG frame. Wilson’s signature starburst texturing is a vast improvement over the OE grip module. WCP320s come in both full size and carry sizes, with or without manual safety cuts and in either black or tan colors.

module helps even that playing field by offering a high-cut 1911-style beavertail, undercut front strap and reshaped, sloping trigger guard that together offer the highest grip possible, allowing for greater control over the pistol, and sight tracking during recoil.

An enlarged, flared magazine well is molded into the frame offering far faster, precision reloads and is compatible with the latest generation of SIG Sauer X-series base pads. Grip traction is also enhanced thanks to Wilson’s unique starburst grip pattern on the grip sides, while aggressive texturing can be found on the front and back straps where it is needed most.

Frame reference serrations are located just forward of the takedown lever—an ideal location to place your support-hand thumb or index finger when it’s not working the trigger. If you’re an X-Five fan and the benefits the tungsten weights the factory X-series module offered, you’ll appreciate the fact that Wilson thought of you as well, integrating internal slots for rod-style tungsten weights that are available separately.

Not only is there a much enhanced, beveled magwell on the WCP320, the lip on the bottom-front edge serves to securely lock the grip of your firing hand in. Front- and rear-strap texturing is noticeably more aggressive than the factory grip model and present in all the right places.

So, with all these added features and benefits, what’s the WCP320 frame going to set you back? A cool $64.95, which is a steal given the improvements that it provides. And you know it’s quality given Wilson’s heritage. To put the price into perspective, SIG’s mediocre X-series grips retail for $59, while the X-Five module sets you back a spendy $119. It’s not all lollipops and rainbows though. Word has gotten out, and as such, the WCP320s are in very high demand, which means they’re going to be tough to find in stock anywhere for a while. They are available in black or FDE. Contact Wilson Combat; Tel.: (800) 955-4856; Web: www.wilsoncombat.com
