B&T USW Conversion Kit for Glock G17/G19 Pistols


The B&T USW-G17/G19 conversion kit is the ultimate add on for the Glock 17 and 19 pistols. It offers the operator the choice of using the pistol in the traditional manner as well as with the built in folding stock, while the transition only requires less than a mere second. The operator can use an optionally available red dot sight and the original open sights as back up.

The B&T USW-G17/G19 Universal Service Weapon Chassis converts your Glock pistol into the Universal Service Weapon configuration. The USW is the size of a normal duty pistol but extends the range, accuracy and effectiveness of your handgun to that of a 9mm submachine gun. It is ideal for any situation where the chance for a longer distance shot is possible.

This configuration will enable the operator to effectively and accurately engage targets out to 50 yards and beyond; that is more than double the effective range of a service pistol. Distances that were thought to be impossible with a standard handgun. There are no modifications needed to the weapon. The whole installation takes about a minute. The USW Upgrade Chassis has an integrated standard Picatinny accessory rail for a light/laser and the folding stock. It is still ambidextrous in handling, with the ambidextrous slide catch lever and reversible magazine catch. The folding stock folds onto the right side of the weapon, where the stock release is also situated. The stock can easily and safely be operated with either the left or the right hand.

The USW Upgrade Chassis is not a firearm and thus is not serialized and can be sold and shipped with no restrictions.

The USW will enable the shooter to produce very tight shot groups at 25 yards and to place first round incapacitating hits at distances beyond 50 yards. This is possible even under the stress of a life-threatening confrontation.

Fits: Glock 9mm, .40cal, .357 SIG Pistols | Gen3 Gen4 Gen5
Will NOT fit railless Glocks Gen1 or Gen2

NOTE: Before installation you must first register your pistol with the ATF using ATF Form 1 as a Short Barrel Rifle.

    Does the USW work when a slide has Suppressor height sights installed?Looks like it could possibly but maybe not.

    Very well made, and I believe worth the money over some of the other braces or stocks.

    Def the coolest of the Glock chassis and as with all B&T its supreme quality. Hard to tell but it has a cutout for the irons in the back although for any real functional shooting you will need a red dot. The Aimpoint Nano was developed with B&T and is available from some US dealers like Tar Heel, but my correspondences with Aimpoint they tell me the Acro is a significant improvement. I highly recommend this if you wanna form 1 a glock into a killer gun that fills a unique role. Thanks Arms Unlimited!

    USW-Glock Conversion

    Pretty happy with the kit, I’d say it turns a Glock into something more like a TP9 than a functional equivalent to a USW-A1. It is slightly larger than the A1 and isn’t really something you would holster anymore-perfect laptop carbine though and the Length Of Pull is more comfortable than the A1. Nice quality and a better value for the money than a comparable product like a Micro Roni or KPOS. Solid lockup with the host pistol frame.
