Chambering the first round, a slingshot modification

[hardluk1]

I have cm9 and cw9 . And the the cm9 racks like a well used 1911, s l o w l y rack the slide and it chambers great. The cw9 is like the first part of the video and after following a couple looong treads yesterday I sanded all three mags down 6ths and found they all still will hang a bit racking slowly. Not as bad but not like the cm9. Still pull it back and let it fly and the cartidge is chambered!!

Have anyone thats tried this sanding of the follower sanded thru one yet. Any breakage of followers yet.

I've had one modified follower break in my CW9, but it was the follower skirt that broke while testing a different spring to give eight round capacity. All the followers used with Kahr springs are still working fine

PM9 Magazine Mod

I just did this mod on my 6-round mags and now I can easily slingshot the first round in a full mag. I sanded like in the photo until there was no step or break where the round sits. Increased the angle slightly also. Now, I need to do my 7-round mags too.

Thanks to the OP for this info!

FLBri:
John, in my view, "some ammo casings have less taper than others" is simply wrong as all same caliber ammo is made to chamber standards.

Not true. I've measured various Mfg's rounds and found as much as .005" difference in the taper of 9mm. Fiocchi's FMJ are only .005" difference from back of the case to the front. Winchester WB measures .386" at the base and .375" at the front. That's .011" difference.

I think this "fanning" issue is more prevalent in 9mm because of the taper. We don't seem to see the fanning issue with .40 or .45 because they don't seem to have as much taper, if any at all.

I didn't just dream this up and what you have measured may well be, but know that every cartridge in any loading manual shows the saami dimensions and tolerances.

All ammo is made to SAAMi industry standards and what I consider the best source for this info, not measurements posted on gun forums:

I understand that there are standards. But my actual measurements don't lie.

I've found that polishing the feed ramp using Flitz and a Cotton Cone on a Dremel tool works wonders in helping with the feed issue. With the magazine follower mods and the feed ramp polished, my PM9 works great and is easy to rack the slide for the first round.

Well, I just tried this out and my mag is now feeding like a dream. Its a brand new CW9 never been fired but I noticed the feed ramp/follower issue when i cycled rounds through. I'm still noticing the sequential rounds being pulled out part way from the mag by the previous rounds. I'm guessing this is due to spring pressure as I've already sanded and polished the inner retention lips of the mag.

[bulletdodger]

Maybe the nickel plated cases of PDX1 rounds wouldn't snag on each other so much. The rounds I've been cycling have been Sellier and Bellot FMJ. The brass seems a lot different compared to other brass rounds. Ive never seen Winchester FMJ get so scuffed up in my 1911.

This is normal. Don't worry about it. Go shoot it like you stole it!

[bulletdodger]

I plan to, GOD do I plan to!!! This little beauty is burning a hole in my palm. Believe me, as soon as I can find 9 mil ammo. LOL. Its crazy out there. I swear there's like one small group of tweaked out preppers buying it all up before it even hits the shelves. I'm trying not to get sucked into the mass hysteria but its really hard not to when all I ever see in every sporting goods store is empty ammo shelves. I was in Cabela's today talkin shop with a gun counter salesman and he was telling me of a guy who has over 70 thousand rounds stockpiled. Thats a bit ridiculous imho. I'd settle for 60 thousand myself, I mean 70? really? lol.

Try your local shops. Cabela's and Walmart are the most shopped stores around here. I found 9mm Friday night at a local store and finally got to shoot my new gun tonight.

I did this mod a while back after seeing your results and it's awesome. Thanks.

Re: Chambering the first round, a slingshot modification

My new follower came in and I finally had time over the weekend to implement Greg's mod. I took her to the range today and fired like 8 loads of 7+1 and had not a single nose dive.

I put the extra 7 round spring in my 8 round mag and out of 7 loads or so, it only had two nose dives. I am confident that I will be able to fix that by modding the follower as well.

Over all, I was very pleased with the performance of my Kahr CW9 tonight.

Please show how to fix, having this problem with my mag.
