I was able to try the Chip Mccormick 7 round compact magazines today. I wasn't too impressed with them.
I ran approximately 100 rounds thru the magazine. First two mags I experienced a failure for slide to lock back. That popped up 2 or 3 more times. The follower would ride up above the slide stop stud. After the first 2 failures, I would let slide down and rack it back manually and still wouldn't lock back.
Also, I had my first failure to feed with the Range Officer Compact. The round was a 230 grain fmj and the nose was high at top of chamber. It was the last round in the magazine.
During the session, I fired and assortment of fmj, Federal HST, and 200 grain lswc.
Question. I have a couple of the standard dimpled followers and have thought about trying one them in the magazine. Any thoughts on that?
