B&T has unveiled its new USW-320 Universal Service Weapon Upgrade Chassis. This cool new enhancement converts a Sig Sauer P320 or M17 service pistol into a B&T’s Universal Service Weapon configuration, with a folding stock included.
“Sig’s P320 striker-fired pistol is unique in that it gives the user complete modularity by allowing him or her to change frame size, fit and even caliber by simply swapping out the serialized trigger group,” Jon Scott, VP of Sales at B&T USA, said in a press release. “The USW-320 builds on this modularity by providing a chassis that adds the stability of a folding stock along with ambi controls and an integrated Picatinny/NAR accessory rail.”
Installing the USW-320 takes under two minutes, B&T claims. To do so, you remove the serialized trigger group from the P320 and drop it into the USW-320 upgraded chassis. You don’t need to make any other mods; the serialized trigger group is held in place by the takedown lever. You then transfer the P320 slide and magazine over. That’s it.
B&T notes that because the serial number is on the trigger group rather than the grip module, the USW-320 is not a “serialized firearm” and be sold and shipped without those pesky restrictions. The company also claims that the USW-320 has an “accuracy and effectiveness” similar to that of a 9mm police carbine.
“Operators can produce very tight groups at 27 yards along with effective hits beyond 55 yards” using the USW-320, B&T’s presser says.
Meanwhile, the company also said it plans on introducing a retention holster. The holster will enable the operator to draw and fire the USW-320 in less than one second without the stock extended, with .4 seconds added to unfold the stock.
