Chambering the first round, a slingshot modification

[david8613]

I wanted to ask is everyone doing this mod? looks interesting...

[DKD]

For what it's worth I did do the follower modification on all three of my P380 magazines. It definately did reduce the angle of the top rounds, which in turn allowed for the top rounds to feed more smoothly. I can even hand rack the slide when I couldn't prior to the modification. The modification is even allowing the slide stop loading of the top round with Speer Gold Dots, which it absolutley would not due prior and would jam every time.
I problabaly could have saned a little more than I did, but it is easy enough to remove a bit more rather tha over do it to start with in the first go around. I am going to run another hundre or so rounds before a do any further sanding. I feel with more rounds down range and with the modification will make a major improvement to the cycling & smoothing out of the pistol.

Am I the only one who can slingshot his or her Kahr with no issues or modifications?

I've had my K9 since March and have had no issues sling shotting the slide when clambering a round. This is the only way I've ever done it on any simi-auto I've owned. But the K9 is also the smallest auto I ever owned!

Just wondering if there is any interest in a modification to the Kahr 9mm follower that makes chambering a round via the "slingshot method" much easier and consistent (IMO, enough so that they could rewrite the manual). It also seems to hold the top round better and might prevent loss of the round during loose pocket carry.

Modification detailed in post #12
Note!: While I'm very pleased with the results of these mods, some folks have tried modifying the follower (though not exactly as I did) and not had the same results (to varying degrees). It could be that I just encountered a "perfect storm" with this mod and my particular gun. If you attempt something similar please keep this in mind and be sure to read their posts.

Hey Greg, I was wondering if anyone at Kaur has added any imput on either yours or other members changes to there mags?

Slingshot?

OK--call me ignorant or a newbie, but what is Slingshoting? I read all the posts and nowhere--that I could find--was it ever explained. Can someone enlighten me? Thanks!

[manalive]

Got it! (Had it all along!)

OK--I watched a video and now know what the term "slingshot" means. I've been doing this for 25 years with my semi-auto's--just didn't know what it was called. :-)

You pinch the slide, pull it back and let go. If you think about the action, it is very similar to the action taken when drawing back and releasing a slingshot - thus the origin of the term. Although with the tough Kahr recoil springs an overhand method sometimes works better.

new to the forum, bought a Kahr PM9 around 12/2012 and love it. I took it shooting Win white box 115gr FMJ and functioned flawlessly even tried racking the slide to chamber instead of slidestop to see how would function and that worked great with my firearm as well.
I expected heavier recoil than it has, and I am very impressed with the trigger and quality of the gun.

Mod on CM9 Magazines

gb6491,
A question please that I may have overlooked within the thread:
Do you recommend the bevel (both sides) along the length of the follower be added back to the area removed by sanding off .06 of the rails?

I just did the mod on 3 6rd and 1 7rd Kahr magazines with relative ease. Must be careful to remove evenly and parallel to surface being removed. I've by hand run rds thru all mags and seems to work fine. I slow chambered both before and after mod and the mod definitely helps. Could not do it before mod.
I might mention, cover the your hands with a towel when removing the magazine spring cover and its inside retainer as this will save 45 mins and many cuss words finding the DAMN thing.

Very informative and apparently helpful this thread. Thank you and the others for spending the time to inform.

Bob,
That's a good point and probably wasn't mentioned before. While I'm not sure if it matters, I did eventually put small bevels on (or at least rounded) those edges on my modified followers.

Greg

I think I will add a bevel back on the follower. It would allow the follower to travel up and be better captured by the magazine case. I think it might raise approx. .040.

[xsailer]

For the record I did add the bevel back on the follower on all my magazines and ran thru 3 sets on two of the mags. No problem and btw the follower did come up from the spring pressure to rest at the top edge of the steel mag.

this is exactly what i did, and it works perfectly. now, if only i could figure out my fail-to-reset problem...

[xsailer]

Kahr1,
I found it near impossible to be exact with the parallel removal of material. That being said doing it by hand is not difficult to do it's just difficult to remove material as machine would. Several folks now, including me and now you, have found after they did it and in spite of the probable inaccuracy, the action works better. So there must be a tolerance one way or the other that is acceptable.

I don't understand your comment "fail-to-reset problem..."

last time out, after about a hundred rounds, it failed to reset- a major problem for a self defense weapon. i got some valuable input from another member, and i should be able to get it handled. i prefer fixing these things myself, as i'm the only one i trust.
