Thread: Do the Pearce Grips extensions for the CM9 magazine decrease reliability?

  1. #1

    Default Do the Pearce Grips extensions for the CM9 magazine decrease reliability?

    I read that some people had reliability issues when using the 7 round mags with the extension. Anyone know if there is the same issue using the Pearce extensions?


    TIA

    I use the 7 round mag as is. I have Pearce Grip extensions on all of my 6 round mags. No issues. Only thing I found was that the mag base lock provided by Pearce was a little thin and I got extra ones that you would find on the 7 round mag from Kahr. They are thicker and hold the grip in place better and tighter. With the thin base locks, the grip had a tendency to slide off with the slightest pressure.

    I have not had any problems with my Pierce grips on my two 6 round mags. I like them a lot and am in the process of changing all my mags over to 6 rounders, all with Pierce grips.

    From what I've read on this forum, the problem is the 7-round mags themselves, even without Pierce extensions. I have other problems with Pierce extensions. I had them on my 6-round mags for a while and had no reliability problems. My complaint was that when I fired the pistol, some finger skin would get pinched in the small gap between the Pierce extension and the bottom of the grip. Also, I found the extension made printing more likely. So no more Pierce extensions for me.

    Where can you purchase the mag base lock for the 7 round mags?
