On my 10mm Match, just about every mag the slide will lock back at random with bullets still left in the mag. Two questions, I think my grip may be the problem. Can any of you post your grip? My right thumb comes real real close to the slide stop with my current grip. Also I'm running an 20lbs spring on a SpringCo Recoil reducer. Could the spring be to heavy? Would it be safe to run an 18lbs spring when I'm running a 165gr moving at 1400fps?
PS: Also running the Henning firing pin block, did it before and after I put the block in. I have since lost the stock block so sending it back to EAA might not be an option unless I get a new block....
