Another magazine modification thread

[peashooter]

After much examination of my PM40 magazines, I have determined that the change of angle on the top of the mag followers is the cause of the evidently common "first round nose dive" problem.
A search of this forum, turned up the 2011 thread about the magazine follower modification for the nine.

Looks like it should work on the 40 too. I am considering doing this to at least one of my magazines. Since it is a modification, and there is the possibility that I will ruin a mag follower, I thought I might just order a replacement follower to experiment on. I see that Kahr offers the replacement part on their website, for eleven bucks, and about the same for shipping.

So anybody else done this on a 40? Any better source for the part? (I don't want the Promag.)

The magazine follower isn't causing the nose dive problem. There are too many Kahr pistols out there that work just fine with the standard Kahr magazine and follower. Remove the slide and and re-install the slide stop. Insert a loaded magazine an check to see if the slide stop is interfering with the nose of the bullet. If it is carefully remove the offending metal from the slide stop until you gain clearance. If that doesn't cure the problem contact Kahr Customer service and send the gun back to the mother-ship.

but muggs is right. What one can do though if he hass the time and know how is to fix sumpin to a part that is really not a badpart but for some reason it makes things work OK. In this case two wrongs might make a right even.

I have suggested one to check to see if the follower is rubbing the mag catcvh button at around round 2 which many report is a cause of misfeed. If that is grabbing, then I suggest sanding the follower, which basically IMO is not the culprit but the easiet thing to fix. Could be an out of spec mag catch button or combination of both, but the easiest fix is the follower mod and not messing around with the button. So hence IMO u fixed a good part that was not really the issue but by doin it, solved that particular issue. Weseeit here alot on this forum and most of the ih house mods these guys suggest are worth of investigation to see if u want to do it or if it will fix ur issues. But Muggs is right.If it ain'tbroke don't fix it goes a long way for me.

Now thyat I have agreed with Muggs on this I must now go outside and Puke!!:Amflag2:

[muggsy]

Puke! Is that why they refer to you the old retch, Jocko? Now it is I who must agree with old Jocko. You can apply a band-aid to your gun. WD-40 and duct tape will fix about anything. And, MD-40 will get you just as drunk as the finest scotch. Just sayin.

I had good luck modding my mags on my CW9. On my CM9, not so much. I am running my CM9 with unmodified followers now, and not having a problem. The nose dive issues I was having when I started seemed to have worked themselves out after 3-400 rounds.

p.s. The Pro Mag 7 round magazines for the CW9 worked flawlessly for me. I did not keep them when I traded my CW9 for a CM9 because they wouldn't fit in the smaller weapon.

[gmcjetpilot]

Please twiddle and widdle on your gun. Then shoot 1000's of rounds
through it, taking copious notes, statistics and pictures, with detailed
drawings of all modifications.

I have about 400 rounds through my CM9 with not, one, repeat not one
faults, aka no faults, zero.

I do the slide release to rack first round as instructed. Frankly it is a great
way to put any pistol in battery. At the range that is how I do it with all
my pistols, since the slid is already locked back.

Last I would never modify my carry gun in any significant way for liability
reasons. In court a modified gun might become prosecution evidence of
your guilt (as stupid as that might be, why expose yourself to it). Albeit
the OP is not talking about a feather lighter trigger mod, anything to do
with how the internals work is risky, not the least it might make it fail. I
always say, don't like a gun, get another gun. Look at any super tiny
compact 9mm or 40, and you will find they all some flaw. Although I
found no fault with my Glock yet, perfect, but for that matter I have found
no operational issue with my Kahr CM9.

However you don't hear about Glock owners modifying magazine
followers, having to slide release rack or worried about what ammo they
use. I think a some of this is too much internet bull. I do think the small
Kahrs with bigger rounds (9mm, 40) are a little harder to operate and
shoot than a larger pistol. OF COURSE the designers have to push the
envelope to stuff the same stuff in a smaller package, meaning more
acute angles and tighter clearances.

As far as the bullets nose diving in the magazine, I don't know. I just
carefully load the magazine, taking care to set each round. I use an Uplula
when I can. After than go to battery with the slide release, aim, pull
trigger and don't limp wrist it....works everytime like it should, like
a hammer drives nails, bang bang bang...

Happy Thanksgiving you all. We Americans have a lot to be thankful for,

Observation of mod. before I ordered several new mags, 7's and 8's, I did the follower mod on two 6 and one 7 rd. mags. Having used all the mags, new(no mod & old modded) a couple of times I haven't have any problems....interesting.

[garyb]

I'm not sure what the mod is. However, go for it. Let us know how it works and what you did to make it work. Pics and/or vids. Thanks.

I am having NO problems with my PM40 mags.

I have Smith&Wessons, and I have Glocks, and as you said, they "work everytime like they should, like a hammer drives nails, bang bang bang..." "with not, one, repeat not one faults, aka no faults, zero. "
I have a Kahr PM40 which does not have such a stellar record, even after a reasonable break-in period. If you have any constructive advice that would help me get the same results from this unreliable PM40, I welcome it.
