rampectomy done CM9 barrel

[CJB]

if it feeds you're gtg

S281 I would bet your gun will run better than it ever has. Mine looks like yours and I have put several hundred rounds through it after the adjustment with no fail to feed or accuracy issues at all. The rounds do not feed from or even touch that part of the ramp that was removed. It is not rocket science, just simple mechanics.

Pulled my PM40 out of my holster to send you some pics for you to compare to. It was polished when it was new, but it runs flawlessly. Hope this helps. Good luck with yours at the range.

My rampectomy is a success --- 150 rounds of PMC 124 gr FMJ plus 20 rounds of Speer Gold Dot 124 gr +P ammo --- zero malfunction and my magazine follower is still intact.

Wow, that was a lot taken off. Glad it still works.

FWIW, here are a couple of photos of a ramp mod that Kahr did on my PM9 bbl.
I don't have a good before shot.
After receiving the barrel back from Kahr, I put a total of 220 rds. thru it using the 5 mags that I have, no broken followers and 100% function.

Glad it worked out for you.

Wow, that was a lot taken off. Glad it still works.

If my magazine spring gets weak and the top round stays horizontal instead of popping up to line up with the magazine lips, I could have trouble feeding hollow point rounds. Right now, the tip of the bullet gets nowhere near the bottom of the feed ramp.

Thanks for those pics JimC, Looks like the rampectomies preformed by some of us owners. It is good to have the comparison.

[S281]

Jim C, thanks for those pics. Looks like Kahr just goes straight across and makes it perfectly flat. Doesn't seem to be much different than the rest of us doing our own. Good to see a factory mod to compare

[JimC]

Well one thing for sure, that's the way one of their people does it.
Maybe the next guy will have a totally different approach.

All's well that ends well. Glad it all worked out.

Sorry but this one caught my eye and I have to play Devil's Advocate....I am just not getting it....because you've had to deep 6 one or more inexpensive mag followers the self appointed "rampectomist" has elected on his own to alter the geometry on an expensive factory barrel with no vetted standards or factory green light on how to do, how much to take off, etc.

I now have thousands of factory and hand loaded rounds through my CM9, have yet to destroy a magazine follower but if I was experiencing a problem, the gun would go back to Kahr in a nano second assuming Karh is not giving away free barrels for folks to practice on. At the very least I would no longer use my CM9 for carry if I did perform surgery on the barrel based on what I think needed to be done.

There was a period in the early Keltec P3AT days crica 2006 when folks were performing rampectomies on their P3AT barrels to cure benign "smilelys" and it became a fad as the thing to do. Whether Keltec ultimately changed the design of their feed ramp (I replaced my P3AT a long time ago when the LCsP came out), I don't know but it has become a practice of the past. There were more than a few ruined barrels back then worked on by folks who should have acknolwledged their own limitations or had their files and Dremels locked up before hand. And certainly IMHO they should not have recommended that other replicate. Keep some extra followers on hand and leave your barrels alone. My 2 centavos, you may disagree. Kahr has good customer service, take advantage of it. Cheers.

The op took it upon himself to try and remedy a problem he was having. No where in this thread did I hear him cry about what he has done nor did I ever read where he was going to hold Kahr responsible if his mod did not work. Instead he blazed a trail for others to learn from. I am thankful for guys like this. They give us insight to the workings of our guns and give us stuff to discuss about here on the forum.

Very well stated Sir.
Your explanation is exactly why my PM9 went back to Kahr for their evaluation after it broke 3 followers in slightly over 300 rds.
Kahr took the action that they did, reworked feed ramp in their words.
I'm sure they would back that action if anything were to malfunction due to it.
