The revolutionary USW concept from B&T is now also available for the P320 and M17 from SIG SAUER. The practical polymer conversion kit transforms a normal P320 or M17 (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 or M17 frame. The USW-320 and USW-M17 lowers equal the full-size P320 and M17 lowers, so 17 round magazines (and bigger) can be used.
