Converts Sig Sauer P320 and P250 Full Size 9mm and .40S&W magazines to fit P320 & P250 Compact models. Works with new style P250/P320 Compact grip module ONLY. Increases capacity. No tools are required for assembly.
I have a P320 compact with the small grip size.I wanted the grip a little longer.This works great with the 17 round mag I ordered with it.And still able to use the 15 round mags that came with gun.Fills good in hand.
