New to your forum so I hope this is in correct category. Purchased a pair of CM's (9 & 40) a couple of months ago as a package deal (VERY pleased with both by the way). Ran into a friend over the weekend that I had not seen for some time. Was telling him about them and he mentioned that he had owned a MK 9 several years ago that he had sold. Then said that he still had a couple of spare magazines for it and wondered if I could use them. Said sure and he just gave them to me for nothing. Got to looking at them closely (they are marked "MK" and "KAHR") and noticed that the followers were metal as opposed to polymer. Just a chrome plated one piece stamped steel follower. Took one apart and measured it for comparison to the polymer one in the CM9 and they are virtually identical. Even the profile on the top appears to be the same. Have not had a chance to try one yet but loading six and hand racking them through the pistol appears to be normal. I am wondering if anybody has had experience with them and if so are they superior or inferior to the polymer followers? If anyone can shed some light on this I will appreciate it. Thanks
