This will destroy your magazines eventually - Tyrant CNC Glock 43X/48 Extended Magazine Release

While it works great at first and definitely works to make dropping a mag easier, it also will chew into your plastic mags where they catch the release. It’s a metal on plastic contact instead of the plastic on plastic like the oem mag release. Metal beats plastic so after about 25-30 cycles most of my mags were so chewed up that they wouldn’t catch the release, and fell right out of the gun. Nothing like throwing away 8 25$ Glock mags. Don’t buy this or any other metal or “milled” extended mag release.
