PM9 feed issue

[mr surveyor]

I wouldn't use a ProMag in a beat up Jiminez JA9 (if they make them for that fine specimen)...actually I did try ProMag in an SKS that turned out to be junk, and have three 30 round ProMags (Beretta 92 style) for my CX4 Storm that don't even make good paper weights

sorry....not a ProMag fan

Another reason I suggested it is probably the magazine, is the issue I just had recently with my Wilson Combat 7 rd mag on a 1911 Compact. All my Wilson mags, and other mags, have functioned flawlessly, and this brand new one would not feed round number 5 - ever. If I cleared the round the remaining two fed fine. It did this 100% of the time. I called Wilson and they said "send it to us and we'll replace it."

So I still suggest you use only the mags that are trouble free with the SD ammo, to confirm your 6 rd mag is malfunctioning and not the PM9.

XZH--sounds like a spring issue. I did not read all of the posts here, but have you replaced the guide rod spring yet? I saw where you replaced the mag spring.

deadhead, yes, I changed the recoil spring as well. I put in a Wolff 20.5 pound spring (extra power). I put it in recently. I really can't imagine that it would be causing a problem...it should be stronger. I might try putting the old spring back in for a test. I am planning on going back to the range 1 more time (today/tomorrow) to test a few theories. I am going to shoot a bunch of SD ammo with the 7 round mag. As was suggested, if it works fine then I can more safely assume that there is a problem with the 6 round mag. I will also re-test the 6 round mag with the original spring to see if there is a difference. If all else fails, I'll call Kahr.

Thanks for the advice so far.

Well I went to the range this afternoon with 50 rounds of SD Ammo (Winchester and Federal). My problem happened only once today and it was after the 3rd shot of the first mag (6 round mag). Again, the slide was back, but this time, I paid better attention and it turns out that the slide stop lever did engage the slide, so the slide was actually locked back. I kept thinking that the round was nose diving. Like I said, it happened only once and with the 6 round mag. I fired a number of rounds through the 7 round mag without any issue. It is not a nose dive problem. It is a slide stop problem, but it appears to be mag specific.

Jocko, if you see this post, please give me your thoughts. I am right handed, but I really don't think my thumb is engaging the slide stop. My thumb hardly reaches it and I checked my hand position and it was a good 1/2" below the lever. Again, it is only happening with the 6 round mag. Before I went today, I switched back to the original mag spring, so maybe that helped. I guess I should call Kahr. Maybe they can send me another 6 round mag to try.

the magazine should not be causing the pre mature slide stop issues. as only the follower can even engage that slide stop lever and that would only be after the last round.Take your slide off and reinstall the slide stop lever and then insert the problem magazne with the rounds that was causing your issues. See if by chance those rounds could be hitting that slide stop as the rounds are being pushed up within the magazine. If your thumb is not doing it and ur sure of that, then it has to be a bad slide stop lever causing it. Nothing moves that slide stop but the follower, but rounds hitting it will engage the slide stop lever, sometimes, maybe not all the times as they may be getting by OK out of one magazine and not out of the other. another magazine might solve that issue also,but check it out yourself. I doubt if it is the magazine springs either.

Check this stuff out and if it is OK then I would give kahr a call and ask them if they will send you anothe magazine (6 round) and you will send yours back to them. But all that beng said if the slide is locking open midway between either magazine, then IMO it can't be the magazine doing it,has to be thmb or rounds hitting the slide stop . The specs on the slide stop could indeed be off just a tad to be cuaing it.

If the rounds are hitting call kahr and ask for IAN and tell him what is going on and he will send you a new slide stop, in the mean time if he does that, just take a small file and look where those rounds are touching that lever on the insdie and just file and smooth that area off a tad. Your not gonna remove enough to see, once the rounds clear, stop. polish and retest... with a new slide stop on the way, u have nothing to loose in experimenting..

I had 3 slide stops replaced on my Para carry 9 before it worked like it should..
