A quick video of my success incorporating Greg's follower Mod

Super follow-up and video on Gregg's modification!

I was holding off but now am going to do the modification on one follower for now and the rest if it is as successful as your video.

Can you post a pic or vid on how you position the mag in the vise to squeeze it? Do you squeeze the entire top of the mag (so it gets squished on all 4 corners), or do you squeeze just front part (rounded bullet end)?

Personally, I pushed the follower down and put a jeweler's screw driver through one of the holes to hold the follower down, and squeezed with a pliers from the top of the mag centered between the rounded side and the back side. Both the mag and the pliers were covered in blue painter's tape to avoid scratching. A few gentile squeezes and the job was done. The first time I tested it, it dropped free. I then took apart the mag, put the follower in by itself and confirmed it slid smoothly and didn't bind. Next checked the ammo went in and moved without problems. It was all good!

I'll bet Greg has a video of it. You squeeze the flat SIDES of the mag up near the top, below where they curve in at the top. You're not trying to squeeze the corners! You'd break welds! The flat sides of the mag are just a hair wider apart near the top, and you are trying to bring them together a little bit to match their width further down. They may be spread apart up there a little bit as a result of bending the tops over. Once that little bulge is taken care of, the mag will drop free.

It's just way too simple of a process...........

As said, the tops of most of the mags inadvertently flared a bit during the manufacturing process. You can damn near near lay it down flat on a sturdy counter top and give a whack with your hand near the top to bring back to where it needs to be to drop free. The dimensions of the corner edges of the backside of the mag actually do not change......that is how little force is required. It's the flat sides that bulge out ever so slightly near the top.

FWIW As far as the cracking I have read about in this forum, based on my experience working with metals in a machine shop (my younger days) I would say the problem is that the metal (for some batches) is just a hair too brittle to take the bend.

See what I do not understand is why Kahr would not make the followers like this in the first place?

Probably because Kahr is not the MAKER of the magazines. From what I've learned, they farm this out to someone else who produces them. Am I right on this?

I can't say ALL manufacturers outsource mags, however, I do know that SIG and Beretta
do. Keep in mind that the design specs and final QC are the manufacturers responsibility.

Agreed, ok gurus why don't they???

I don't think anyone can answer that except Justin Moon, and I wouldn't hold my breath waiting for that to happen. He and his company seem very stubborn on the issue.

Got a free 7 round mag yesterday. Made a quick video of the mag performing with it's original/stock follower versus the modified follower from the previous video in this thread.

Jim:
My PM9 has worked fine using the slingshot technique from day one so I never considered your "mag mod". Today I watched your latest video and learned something. You closed the slide very slowly. In doing that you created a failure to feed. I started to wonder if I ever needed to charge the gun quietly by slowly racking the slide what would happen. Sure enough, I got the same failure as you did in your video. I was using my 124 gr RN handloads. Reluctantly I pulled the follower out of my seldom used 7 rd magazine. A few strokes with 600 grit wrapped around a pencil and I tested it. Perfect. I took it apart again and took another few strokes with 800 grit just to polish it a little. This thing now feeds like a dream when I just barely let the slide home. I did all three of my magazines in less than 15 minutes. I took a much smaller amount off the follower than you did. I can always take more off if necessary but I think I got it. I will take everything to the range Saturday for a complete test. Thank you for your great work posting this.

Glad you got something out of the video. You make a valid point with regard to the tactical advantage of being able to chamber a round quietly, smoothly and with 100 percent reliability.

IMO the smoother a mechanical action is whether it be in a handgun or any other type of device, it will increase both reliability and longevity of the associated components.

9mm ammunition is peculiar in it's flared design, especially in a single stack application. Changing the rake angle of rounds 2-6 in the mag tube (or 2-7 in this case) by changing the angle of the follower, positions rounds 2-6 at angle that prevents nose dives by more favorably supporting the round being chambered. It's a very basic concept that is easy to incorporate if you want some added functionality and reliability when chambering the first round.

The best analogy I can think of is snatching a table cloth out from under a set of dishes. If you do it quick enough, the linear forces involved will leave the dishes intact on the table. This would be akin to using the slide stop or an aggressive slingshot to chamber the first round........the linear forces smack the back of the round hard enough so that it strikes the ramp at a high enough point so that it will chamber. But go slow, and the round drags on the mag lips and dives under the ramp due to lack of support from round 2.

HERE ARE 3 VIDEOS OF MY GUN AFTER I DID THIS MOD TO IT, somethings still wrong with mine, feels very clunky and hard to handle, not at all like the guys youtube.be one

http://www.youtube.com/user/JamesBrownTown/videos

::edit:: also at this link you'll see a 4th video. entitled JAM, this is what happens when I try to LOAD MY GUN by locking the slide back, popping clip in, then releasing. It jams! Hence why I did this mod. What do you think of my slingshot method, and this jam video!

::edit:: when ever I do this, it makes and feels like a clunk then a clunk, then i have to go back over that clunk and clunk again. The idea of my gun ever performing like the video the guy posted a few threads before mine is just beyond me.. I think I just ended up with an old lemon

The mod may not work for everyone

I am on the fence as to whether i am going to do it, especially after the most recent post.


However, if you were an "outsider" watching the video you may not purchase a kahr at all.

An extra follower isnt the worst thing to have around

The follower mod in my video is for a CM9. Your video indicates you have a PM40, hence I doubt there can be any valid post mod comparisons between the two handguns. Additionally, the follower mod is designed to prevent nose diving which does not seem to be the case in your video.
