Chambering the first round, a slingshot modification

[Alfonse]

I wouldn't do anything unless your gun doesn't function in some way that you want it to. Shoot it and enjoy it!

Alfonse- Good advice. That's what I am going to do.

It's a 'given' that 200 rounds is for break-in and mating of parts, and mating of shooter with firearm.

I never did any mag modifications to the CW9 that I had for 5 years. Indeed, I did have jamming problems with the CW9 8-rounder, but not really with the 7-rd mag.

Perhaps by merely shooting the new PM9 the probable hangup of follower encountering resistance by the mag catch will work itself out through 'wearing of the parts', reducing friction.

I am a bit disappointed that I could not rectify the anticipated problem by following Jocko's last instruction re magazine mods in the 'Proper prep of a new Kahr' but that's the way it goes sometimes:

"MAGAZINE FIX: some have reported that their 2nd or 3rd round tends to nose dive in their kahrs. Here is what is happeing, as the magazine follower is moving upward when it hits that area where about round 2 or 3 is still in the magazine, that follower is now in that magazine slot hole where the magazine button locks into it. That magazine button is actually stopping that follower from sliding past it without any hindrance. Now I can tell you the fix but if you will just go to the sticky by GB6491 on CW fixes, and scroll down, u will see in with a great photo tutorial how to fix this issues. It is a peace of cake. A quick test to see if u have this issue, is unload the magazine, take the floor plate off the magazine and pull the spring and follower out of the magazine. Now insert the empty magazine in the gun until it locks in place. Now with the spring still under the follower insert it slowly in the magazine upward and feel for a stoppage before the follower gets to the top of the magazine. If u feel stoppage, then go to GB 6491 sticky and see how easy this fix is. OR pull the follower out and sand the right side of the follower back alittle where it comes into view in that magazine slot opening, smooth it with 600+ grit paper and retest, It will not take much to get clearance.. I would even recommend one to pre-test this out before going to the range. will take 5 minutes to test out. Get ur gun prepped right and all the little tid bits of information that this forum can supply before that first range trip and it will be a big success... This magazine fix is usually the culprit in 90% of all NOSEDIVE ISSUES."


Thanks.

Update: Maybe I msunderstood where to sand it. Now I am thinking that it's really the front part of the right side of the follower that should have been sanded down. That is the part of the follower that shows in the magazine slot opening located on the side of the magazine tube, more or less AS STATED by Jocko. I'm going to try it. I originally sanded the right side of the follower from about midpoint on to the rear. Duh! Now I realize its really the side of the right 'leg' that drops down!!!

The gun has yet to be fired.

Difficulty solved. Sand the area on front right side of the follower, e.g., the 'leg' that drops down. Actually sanding the edge of the leg, perhaps a bit above it as well.

Only takes a minute or two or a few minutes as stated. I used 500 grit because I did not have 600.

Worked well with my 7-rd extended magazine for the PM9. Now I've done it on the followers for the 6-rd magazines, which took me longer going back and forth to check in seated tube, no idea why, don't care.

Anyway, that's at least one potential problem solved- the follower should not hang-up on the mag catch during the last rounds.

200 round break-in would likely resolve this on its own, but who needs those type of jams, anyway? I certainly can do without them if I can help n*i*p* them in the bud.

Thanks, jocko and Kahrtalk! Much appreciated!

Or, you could get Alfonse's metal follower for $20 and not worry about it. Problem solved.

FWIW- Found this in the FAQ section on the Kahr website.

"

• Q. My firearm fails to chamber the first round when I pull back the slide and release it. What is wrong?
  
  A. It is likely you are either failing to pull the slide fully back or you are riding the slide as you release it. We recommend that you lock back the slide, insert the magazine, and release the slide with the slide stop. This will require that you carry a load in the chamber for self defense purposes. However, the passive safety system will prevent the pistol from firing unless the trigger is pulled, even if the gun is dropped...
• If you would prefer not to carry a round in the chamber, you may remove a round from the magazine. This alters the angle of the bullet and will allow it to chamber even if you ride the slide. " [Emphasis added].
