Absolute trash - Lockstep Arms Glock 43 Magazine Release

These things are so out of spec, they shouldn't even be sold. I'm glad that I had tried the fitment on a magazine before installing it, because if I had somehow managed to shove a magazine into the magwell with it installed, I would have had to destroy the magazine to salvage the frame. This magazine release is so narrow, it sits inside the notches of the magazine with no side to side play. It will only work with magazines that have the release notch cut out, but good luck even getting the magazine past the tapered portion without a significant amount of force.
