This has been a common complaint. Some peoples finger extends far enough past the trigger to rub on the magazine release. Either try to use just the tip of your finger when shooting (best) or you can file just a little bit off the top of the Mag release...hberttmank said:The only thing I don't like is when I fire a lot of rounds my trigger finger gets sore on the very end from rubbing the mag release. I wish they made the trigger just a little bit larger. Anyone else have this problem?
