Hands On With the B&T Grip Module for the SIG P320

At the NRAAM in Dallas I had the opportunity to check out the new B&T USW Grip module for the SIG P320. I’m a fan. It felt well-made and looked great. For those of you who haven’t seen it before, basically it’s a polymer grip module with a side-folding stock that accepts SIG P320 frame inserts and parts.

To build the USW Grip Module all you need to do is move the trigger group, the slide and the magazine release onto the USW-320 frame. Pretty easy.

The USW Grip Module is probably going to be a popular SBR choice for From 1 builders. According to the B&T website the USW Grip Module is available as of April 2018, but I have yet to see one in stock anywhere yet.

And before you ask, no it doesn’t take GLOCK mags or an arm brace.

  1. That would make it illegal in n.y.

      Is *anything* legal in New York?

      It’s a self-populating prison. The same people left a long time ago.

      1. They do let us think sometimes , but not when we vote

    Add an 8-inch barrel and a can and you would have something interesting…

    Or…$250, no stamp, and surprisingly solid. You can drill and tap your own setup for a 2” pic rail to mount a small 3x magnifier.

    With a G40 and Vortex Venom, even without a magnifier, hits at 60-100yds on 6” steel are practical and a world of fun.

    For those interested in a shoulderable platform for the P320, check out the Fire Control Unit (FCU, it’s the name of the company) Exo-One (X01). Similar idea but a bit more like the Glock carbine conversions. Except it has a flattop pic rail for stationary mounted optics, an arm brace (no SBR tax stamp), and is a bit more of a stable platform

    All the negatives of a long gun and all the negatives of a pistol!

      Absolutely, in most cases. The author (below) went through the pain of buying a variety of chassis systems (he calls them enclosures), SBRing his G19 as a test platform, then testing them all out. He eventually gave up on the idea, frustrated with reliability issues, and removed his G19 from the NFA registry (without a refund). This article is the summary, but it’s worth reading the articles that led up to his conclusions.

      I handled a few of the newest chassis models at SHOT 2018 from IWI, IMI, Mako, etc. They felt like a step-up in quality from previous generations, but I hold my doubts as to the issues the author of the article described. When you narrow down the physical space that an empty can eject away from the pistol, you’re gonna have issues.

      I see two types of practical applications in these pistol platforms. The first is dedicated PCCs, such as the MPX, Scorpion Evo, Ruger PC Carbine, etc. Super low recoil, portability, increased muzzle velocity (even good enough for deer/hogs/bear, such as with a 10mm or .357Mag with an 8-16″ barrel), and far greater stability from a standing platform for better accuracy at the practical limits of the round itself (I limit myself to 50-75yds for ethical shots on game, but I wouldn’t hesitate to defend my family at 75-100yds with a PCC, if required and a real rifle wasn’t available).

      The second is in taking a pistol you would otherwise carry (whether open, concealed, in a vehicle) and give it a little boost in stability. For me, that’s a G40 in the truck. By adding a 1Shot brace, I extend my practical range on deer/hogs from 40yds out to 75-80yds. The designer of the 1Shot was at SHOT showing off a model he made for his S&W Shield, with some video footage of popping steel plates at 75yds far quicker and more accurately than I could ever do free-hand.

      Installation of the 1Shot takes about 2 seconds (grab it, align the grips, done); if I then need to holster the pistol, disassembly is about 1.5 seconds (maintain a grip on the pistol, remove the 1Shot). For this application, I won’t accept the decreased reliability of a clamshell/chassis design that restricts the ejection port in any way. This B&T design, or the 1Shot, has zero effect on reliability. In fact, I argue it increases reliability by providing the pistol a more solid platform (your shoulder) to recoil against; the pistol’s frame is more stationary, having the effect of a shooter providing a firm grip vs. limp-wristing.

      One downside to the B&T and 1Shot are the weak cheekweld. Especially with a micro reddot mounted on the pistol’s slide, I find that my chin and lower cheek are battling for some space on the stock or buffer tube. I mitigated this with a cheekpad; it’s still no rifle stock, but it’s a practical enough gain for the slight discomfort.

        This is starting to look like I’m a 1Shot employee. I paid my money and just like the product. It’s limited in utility, but that little slice of practicality works really well for me; it’s single truck gun that works for close encounters as a stand-alone pistol, but then I can add a brace for taking some game to feed the family. If B&T somehow makes a braced model, I’ll be doing a .45 ACP P320 version ASAP.

        Funny how you leave out that they tested the $100 Endo/KAK combo

        Sounds like you’re a shill

        1. avatar Anner says:

          That’s another good option, especially for the price, though I haven’t handled one myself. My one concern would be how stable a manner in which it attaches to the pistol, since it’s just using the small gap between the magwell rear of the grip and a pin through the lanyard hole. As long as that’s a solid lockup, it’s probably a sweet setup.

    If the frame allows clearance for the P250 hammer, this little setup would be more interesting.

    1. avatar Anner says:

      Are the fire control groups for P320 and P250 mostly the same, in terms of dimensions? The P250 obviously has the hammer hanging out the back, but would you expect a P250 FCG to fit in a P250 frame and then function as the trigger is pulled?

      1. avatar TomD says:

        They use the exact same grip frame and mags…so I would say yes.

    Do they market a holster for this rig? Sounds like police and military are the primary customers. They’re going to want a complete setup.
