The Shield Arms Premium S15 Steel Mag Catch (brand part no. G43X-PRM-BLK-LH) is optimized specifically for left-hand use on the Glock 43X and 48, and it is not an ambidextrous catch. Because Shield Arms built this catch for one-handed orientation rather than trying to serve both, they were able to eliminate the hard angles found on the bottom of an ambidextrous catch, giving smoother reloads when paired with their steel S15 magazine. The catch face is also extended by roughly 0.03 inch compared to Shield Arms’ standard mag catch, giving slightly more magazine engagement for a more positive lock-up on every reload.
