The Shield Arms Premium S15 steel magazine catch is built for Glock 43X and 48 pistols running Shield Arms S15 steel magazines. This left-hand version is not ambidextrous, which let Shield Arms remove hard angles for smoother reloads. The face is about .03 in longer than their standard catch and gives slightly more magazine engagement. It will not work with factory polymer magazines.
