Replace the standard scrap black mag with stainless Kimpro, Wilson combat or chip mccormic mags. You could take your standard mag to a gunsmith & have him file the lip on the follower but..... Check your feed ramp to see if it has any marks from follower also. It sucks that you pay more money for a custom gun & they give you a junk mag with it. Don't forget to follow break in instructions & keep record of round count for spring replacement. I carry my Pro CDP II everyday & love it but I also have Kim Pro & wilson combat mags for it.
