Howdy and congrats!!! Is yours new? My plate move a litttle, but not much on my cm.
didn't they start putting two screws on the 380? You can snug it up, I cant remember the size driver but be carefully not to over tighten.
Congrats! Mine was a bit loose when I first got it but a quick tighten and it's stayed that way. And, just FYI, mine was moody for the first 300 rounds. Now it's flawless and will shoot any brand of ammo that I've tried.
