new cm40 follower destroyed

In all interest these followers are not designed right, I’m not sure of the material that these are made of, but it looks like a shear point in the picture. The quality has to step up, the tolerance has to be better the feed ramp is wrong. Don’t get me wrong I like the gun (I have the CM9) but the same issues always to come up with breaking or feeding problems. You can have a good gun design but if the magazine is crap then the does not function. So with all the design capabilities that kahr have why don’t they work on this issue. I would really like to see someone like Wilson come in and start making mags for kahr ,the mags wilson puts out are the best going, zero problems with any 1911 mags. It is a shame that you have to make the gun function with problems and your work and time. Just doesn’t seem right to me. I’m getting a little frustrated too, I’m going to make my own follower to make things work the way they should. It will not be easy but if this works I will be sure to tell all of you. That’s my two cents worth

ok jocko this one is for you. as i mentioned before when i first shot the gun i loaded 5 rnds into the mag shot 2 rnds fine. ejected 2nd casing and slide jammed on top of third case. if you look at the pics i posted you will see when the mag has three rounds in it the follower is at the mag latch spot. what i believe is wrong is the mag release part inside the frame sticks to far into the mag and catches the front follower lip snapping it off. i believe the reason the slide jamed on top of the third rnd is because when the mag release caught the follower and broke the lip off it slowed the mag spring down just long enough for the slide to return before the round was back in position..... i may be wrong but just picture that and let me know what you think.

I looked at my mag followers and noticed a definite scribe mark on the side where the mag catch goes through the mag tube. The follower is dragging past the mag catch when the follower moves to 4 rounds left. And then the front leg of the follower moves to that spot when there are 3 rounds left. Those numbers are for 9mm.
I took a photo with my macro lens that I hope to post tomorrow if I can find a minute.

Ok, so here are the photos that show that follower is dragging past the mag catch. Keep in mind that the macro photos make the scratches look much bigger than they really are. And my CW9 has never had an issue, so I'm not worried about these scratches, but it might explain why some guns have more feed issues than others.

the mag catch is not what isw breaking the followers though. I have posted before in the kahr tech secion how to check for a grabbing mag rlease button. It is an easy fix, very easy if u just follow my fixes listed. That follower ust glide up ad down with no restriction or it will upset the cyclyiong action of ht gun. It willhappen around 2/3 in the 9's and probalby the smae in the 40's. I think though we are taling about two different issues with the busted followers, that is IMO feed ramp caused. My point here also is that some mag release buttons will grab more than others. Like orenzo posed,his is barely hitting the follower, and so he feels he is OK, that is a shooter decison. I myself want total free play whent hat follower slides pas that release button. It is easy achieved. Most kahrs do not have this issue but in my opinion when one reports that at round 2/3 it nose dives that tellsme u couldhave a follower grabbing the release button. We really have no clue eiter when the gun is loaded and the sring is compressed what all that polymer follower is doing in tha ttube either. It just should not e grabbing period, Now whether that is ones issues is maybe iffy for some but IMO, it is sumpin that a shooter shold want to eliminate as a possability to.

It is an easy pu$$y fix.

My poit here is also, some magrelease will grab more than others. some might makr

i somewhat tested the feed ramp theory last night and im not so sure that is it. i painted some pullets with marker and cycled them through the gun looking for any paint missing or bothered and the only thing hitting the bullets is my slide lock.

I don't believe the ramp should can touch a most bullets when cycling unless a wide profile tip and have it pushed forword in the mag. What happens when the slide is locked back some extra pressure is placed on the barrel and the empty mag is then slid in slowly till the follwer pass's by the feed ramp. If your slide lock is rubbing bullets sound like it might need some filing back?

I have been lucky with my CM40, after a few hundred rounds, I have had no issues, not even a hiccup. But, before I shot it, I followed the sticky and stripped it down and checked clearances before ever even loading the mag.

I also believe that the .40 S&W small sub compact guns have more issues than 9mm or .45 ACP due to the power of the rounds. A .40 is loaded to 35,000 psi just like the 9mm but MUCH heaver rounds (for the most part) and the .45 is loaded at 21,000. That is A LOT of bang at that pressure in such a small polymer weapons. I have seen shield .40's and XDSC .40 have more issues than the 9mm siblings. But saying that, I love the .40 round, its my choice in carry rounds.
