I hate this trigger - Elftmann Tactical Elftmann Match Trigger

Put this in a DDM4ISR as I have a friend that loves his Elftmann triggers and it fails to reset on 3-5 rounds out of every 30. Sometimes I have to wiggle the trigger left to right and I'll hear the reset click so I can fire it, but this isn't a failure to let off the trigger, I'm moving it from side to side for it to reset, not forward and back, that's not normal. Most of the time, however, I have to rack a round and watch a perfectly useable round hit the floor in order to get it to reset. This is worse for subsonic ammo (I've tried several manufacturers), but I can barely get through a mag of supersonics on this trigger without an issue.

It sucks when you're range shooting, it's dangerous for life saving applications, and it would be terrible at competition shooting.
