I just got my XD45c and loaded up the two compact magazines yesterday. I noticed that when I put the magazine in the gun (fully loaded with ten rounds) that one of the rounds is loose and shakes back in forth. It also does this if I push down about 3/16" on the top round, as I am sure it is pushed down in the weapon. If I chamber a round and then have in the 10 round magazine, it does not do it. Nor does it do it when I have a 9 rounder in. I use the Pearce grip extensions but switched out and tried the original plates with no change. I have two compact magazines and it does it with both. Anyone else notice this or have a fix for it?
