The perfect upgrade for the SIG Sauer P320! The revolutionary USW concept from B&T is now also available for the P320. The practical polymer conversion kit transforms a normal P320 (full-size or compact) in less than two minutes into a USW-320 with integrated stock. Just transfer the trigger group, the slide and the magazine release onto the USW-320 frame. The USW-320 lower equals the full-size P320 lower, so 17 round magazines (and bigger) can be used. Due to the integrated folding stock, accuracy and range is improved significantly.

*Grip module and stock only.

NFA NOTE: Under federal law, attaching a stock to a firearm with a barrel less than 16” amounts to making a short barreled rifle (SBR). Prior to making an SBR, the owner of the firearm must first register the firearm with ATF and pay the appropriate tax. Please understand your applicable laws prior to purchasing; it is the purchaser's sole responsibility to obey all applicable laws.
