Grams Engineering's slick follower-and-spring kits typically add +1 round to your factory magazine capacity. However, the slide will not lock back on the last shot. This kit fits the Sig Sauer P320/P250, 9mm/40SW. Can be used with mag OAL that measure up to 145mm long. (Includes Grams Format Follower & 11 coil spring.)
