Very easy to snap them
As another review mentioned, these break very, very easily so be careful installing them. I snapped the first one I tightened using only finger pressure on the end of the Allen key. If one were to use the short end of the Allen key in the screws and try to torque them to spec, they would all undoubtedly snap. Also as mentioned, these are Beretta bits, so it certainly isn’t LT’s fault. I had no issues with mags releasing or binding when installed with the LTT VZ ultra thin grips. The o-rings are perfect for these. I wouldn’t continue using these things if they didn’t look so nice on those black grips. They shore is purty…
