rampectomy done CM9 barrel

[muggsy]

+1 Kraigster, with the unauthorized modification the factory warranty is void.

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.

I am not doubting that this is interesting discussion. Equally interesting would be to know what Kahr's position is on this and whether there is any intention on their part to modify the design of the feed ramp. My guess is, that it would have to be systemic issue before they would take any action. As I said earlier I and so many others have had thousands of rounds fired in their CM9 with a nary a problem. And I would not sacrifice an $$ barrel (unless I had a spare on hand) for the sake of a magazine follower.

At the very least IMHO, the OP has an obligation to advise members that that performing any modification on the CM9 barrel other than refinishing or polishing of the feed ramp and throat up to the rifling is NOT a factory sanctioned mod, will void one's warranty, and is done at the owner's risk.

I am all for interesting discussion but with it comes a responsibility on the part of the author to include any necessary caveats.

Lighten up. Does a mod really require a warning label? He did the same thing in 20 minutes that the factory would do in 3 weeks.

Having Kahr perform the work doesn't void your warranty.

Doubt this will either. They gonna notice it isn't factory? What if I buy another barrel and put in it does that void warranty?

I agree...I'm outta here.

Many can do it but I have never santioned a ramptecomy. It willgive kahr and any maker an out of u do such a mod. They can back away from a magna ported barrel even, and even they sell their own ported barrels. Give any maker an out and they might choose to take it and IMO u have no recourse. There are some lines I fee one can corss and be ok with factory warranty, such as changing sights etc, recoul springs r a owner thing also, screw tith the trigger bar and I think u crossed the line. MY PMJ9 is highly moded but I knew that goin in also and was prepared if I had any issues to pay to make the gun right again. Grip stipplyling could also be a mod that a maker can walk away from. But for me anything u do with the feed ramp utter than polishing it u should let the factory do it. 99% of kahrs need no feed ramp mods , so if ur gun is breasking followers, then let kahr fix it. They made it. Many years back it was a normal procedure on the kel tek forum and I think that is where the term RMPECTOMY surfaced even. I never heard of kel tek ever voing any warranty over it either for they knew they had an issue but really never stepped up to the plate for a few years to do sumpin about it, so there fore RAMPECTOMY was born..

True but a reasonable hand and deft touch would be indistinquishable from original factory work.

[CJB]

Part of the Magnuson-Moss act about warranties says that a manufacturer has to show why non factory work made the warranty void.

That is to say - if you stippled the frame and the gun shoots low, they have to show how stippling the frame made the gun shoot low for the warranty to be voided. If you do a ramp shortening, and have trigger bar issues.... same thing. They gotta be able to show how A effects B. On the other hand, if you do a ramp shortening, and have feeding issues, its a no brainer for Kahr to say sorry, the pistol was tampered with, and we can't warrant materials and workmanship against work performed by third parties.

Before anyone works on, or modifies a firearm, their mindset really ought to be one that accepts responsibility for SAFETY, FUNCTION and ACCURACY, in that order. If you're not willing or able to take responsibility for any one of those three items, then you have no justification working on firearms.

What did I miss with this?

Do you really believe that a tech at Kahr wouldn't be able to tell if a guy took a Dremel to the feed ramp of his barrel and was then reporting problems feeding or otherwise?
Some Dremel tool owners shouldn't own firearms and some firearm owners shouldn't own a Dremel tool.
Put the Dremel down and move away from the gun applies to many!
Some very inexperienced gun owners read about fixes on the Internet and after reading them a few times, think they are qualified gunsmiths or armorers.
In the case of my PM9 I felt that it was Kahrs responsibility to address my PM9 breaking three followers in -300 rds.
Could I have done it? Yes but I chose to send it in on their dime and have them do it and yes, it's still under warranty.

It's like a guy back in 2000 or 2001 that bought a Bar-Sto semi-fit barrel for his G17L. He didn't realize that semi-fit meant that some fitting may be required. He read about barrel fitting on Glock Talk and began on his...long story short, he screwed up that barrel that cost about $250 at the time. When he contacted Bar-Sto, they offered to sell him a new barrel and suggested that he have them fit it.

So whats the point ....

I said reasonable hand and deft touch, and you described gun-hacks. I'm not connecing the dots here.

And no...Kahr wouldn't know that maybe ten 1/1000ths were cleanly taken off the ramp. Evidence of factory is already there in many pistols.

I will stand by my safety, function, accuracy statement.

Almost every one of my favorite handguns and carbines has benefitted from my Dremel work. I started working on cheap KelTec's that really needed the work and improved because of it. I wasn't too worried about screwing up because a replacement part was not expensive; even the whole gun could be replaced within my budget. I had grown tired of sending these guns back to the factory for simple work to get them to function and make them reliable. Eventually I just gave up on the brand entirely.

I have returned many guns to the factory for them to do warranty work or work that I choose not to do.

However, I took those skills I developed on those cheaper guns and started working on my Kahrs and Berettas and then some carbines to polish various different parts and make adjustments on others. One of my most common adjustments is to work on a slide release so that it releases on the hard insertion of a magazine. I've done this on a dozen or more pistols.

I am not a gunsmith, metal worker or mechanic. I am a home hack, self and internet taught. I have not ruined anything I couldn't fix using my Dremel, files, wet/dry sandpaper, belt sander, stones or anything else. I have made my guns function the way I want them to. They are more reliable. They are easier to shoot and in many cases they look a lot better. I have done trigger jobs, slide melting, rampectomies, installed different sights, reprofiled bolt handles, adjusted safeties and slide releases, and generally polished every piece of metal that slides against another piece of metal wherever it may be in the gun. Doing such work gives me a pride of ownership and involvement with my weapons that is invaluable to me. If I ever screw up and have to replace a part, or even the whole gun, I figure I'm already way ahead with what I've $aved and in the satisfaction I get from doing this work.

When I was young and at a boarding school I used to cut hair for some pocket change. I learned that you could always take more off, but you couldn't put it back. I just follow that same rule whenever I work with metal.

A person of average intelligence with some decent tools, including a Dremel, and reasonable mechanical skills can work on his own guns and not destroy them and not void warranties and not cause the problems that some posters think are just so terrible and happen all the time.

Sure there are a few idiots out there who ruin guns. Walking through a gun show will reveal the work product of many of these home hacks. They are easily identifiable and sometimes a real bargain to pick up and then fix. At the very least they are fun to look at and try to conjure up what was going through the individual's brain when he did that work the way he did. It's kind of fun.

Bottom line: If you are interested in trying to do this type of work yourself, go buy a cheap screwed up gun at a pawnshop or gun show. Buy a Dremel, some files, some 400 and 800 grit wet dry sandpaper and go to town! Have some fun. Learn something. If you screw it up even worse, and find that this is not where your talents lie, give it up. However you may just find some real satisfaction in working on your own guns.

My barrel came polished from the factory new. I doubt Kahr will penalize this guy for polishing his, they may even think they had polished it before shipping and not think twice. Unless there was a certain serial number where they started polishing the barrels before shipping?
