button is a touch oversize for thumb access. install was fiddly only because the mag catch came pre staked and i had to back the catch screw out a few extra turns to thread the new button on. works fine once seated
TruCalibre enhanced mag release button comes with the matching catch which is convenient. Drops in cleanly. Anodize matches mil-spec parts. Button extends just enough to drop a mag with the trigger finger without accidental presses during recoil.
