CM9- getting mags to drop free

[kayl]

I read the thread about squeezing mags down to size, but all of my mags are already down to size. I also took some sandpaper and sanded down the "rails" inside of the magwell a little bit.

The mags drop free when they're below the mag catch, but they stick up above the catch.

Any other fixes? I don't want to go too crazy sanding the magwell; I might just ask Kahr to fix it :-p

The bulge that gets squeezed is at the base of the "lips", at the bend transition to the very top of side of the mag.

Look down into the magwell and check the mag catch surface that passes the front of the mag.
If it has a shiney spot, remove it and file/stone it for some clearance.

I wouldn't mod the frame/magwell, but that's me.

agree with Tilos, last thing I would fokk with is ther frame magwells. U can't put back what u take off i that area. At the worst u can just ruin a mag well body

[kayl]

Hrm-
I thought touching up the magwell was the norm-
I won't do any more to it!

I'll double check my mags tonight!

I couldn't get the mags to drop free, so I sent Kahr an email. The reply I got stated that the mags were out of spec and offered to exchange them for new mags that will drop free.

Hopefully that's the case, but I find it hard to believe that all 4 mags I have from 3 different sources are out of spec.

best fix for this is to use pliers and squeeze in along the top of the magazines (squeeze together the left and right side) along the entire length

squeeze, drop test... if fail squeeze some more, rinse and repeat

so far this fix works on both of my mags that i recently purchased

good luck

Sorry to hear that.
The bulged area I mentioned is only .003-.005 inch bigger than the rest of the mag width.
How did you measure those mags to determine they are "already down to size"?

my PM9 didn't come with calipers or a dremel tool. What should I do?

Digital calipers.

Where exactly is the area? Right below the lips, right?

I doubt that Kahr is going to "fix it", because their design is to NOT have the mags drop free.

Other threads note that Kahr will do something to allow a drop free mag if you send it in and request.

Why would Kahr CS say that the mags are out of spec if they aren't dropping free if that is how the gun is designed?

Interesting that my new CM9 was sticky at first (I have only 100 rounds fired so far), but yesterday I was dry firing and as long as I pressed the mag release button COMPLETELY IN, the mag dropped without sticking. That would suggest that the mag release just needs to wear a bit????

......this observation illustrates just how little movement/force is required to "squeeze" a mag so that it drops free.

[jocko]

not sure that is true

probably more kahrs drop mags freely than not. The guru's here have found that it is more magazine related than mag well related. and there is a very simple fix for dropping those magazines if one has to have it that way. Mine have never dropped freely in my PM9 since day one and I know the fix but choose to leave it as it is, as I don't fear that magazine flyng out of the gun if accidently the mag release is pushed in. each to his own though.

I would try the fix before ever shipping it back to kahr...
