Greetings to all on Glocktalk. I'm a newcomer to the forum -but not to its main subject!! Recently, I bought some "Pierce Grip +2" floorplates to add to my hi-cap G20 mags, but the very first one I tried caused the magazine it was installed on to become totally unreliable. The follower dives forward after firing 3 or 4 rounds from the fully loaded magazine, buckling and jamming the spring to the point where I have to drop the floorplate to remove the now free-rattling rounds. The magazine returns to the usual Glock Reliability after re-installing the factory floorplate. Whats the problem?? Any solution & suggestions welcome! Thanks in advance.
