Thanks for the reply. Mine has never been on first round. Usually mid mag. Looked at my feedramp and chamber and it looks clean. I am waiting on a new follower and will test extractor mod. Tension was so tight I am thinking this might do it. Thanks again.

in sheepherders

Only cowboys can say yahoo Jocko, I'm not sure what sheep abusers say but I'm sure you'll think of something inappropriate.

Maybe it's an imitation of a back up buzzer on a truck.

talk it is called baahoo!! Just sayin Must I explain everything to you??? Just sayin

[jocko]

not so

Do you see my point. With the porting, some if not most of the energy is released at the port. In the 4 years I had a malfunctioning gun I didn't want to do anything to reduce the recoil. Now that it is running, I don't want to make it not run.

I wouldn't mind a smoother running gun, do I need more flash flaring up? Particularly my handloads seem to flash quite a bit.

Kahrtalk where information comes from the heart and head but has to be re-translated.

some by magna ports test is around 6% drop in velocity, certainly not most. Porting will not effect reliability

sure doesn't sound like extractor issues but if u do the mod, just take off no ore than about .020 off t he long rod i thge extractor channel. and t hem polish thgat extractor eally good. takeing off this smll amunt will not screw things up either, but it will releave some tenstion, and at the worst u have just runed that rod which is replaceable. When u see fromn custom gun smiths the word "tensioning" the extractor, this is what tey are doing.

Thanks for the reply. I have already done the mod. Just rounded the edge and smoothed it to a nice radius. Going out to shoot it now. I am very familiar with tensioning and tuning the edge on the 1911 extractors. Have also done a little with a couple Glocks. We will see how I did with my Kahr.

Update. Was hoping follower would come in this week as I called Monday and they said they would send one right out. It didn't. I bought a new mag at LGS so I could go out today and try her out. I did the radius of the extractor (thanks 100 percent for the tip) and did take a small amount off the feed ramp and re-polished it. So out with another 200 rounds today. No more failures to feed. Only issues were a couple slide lock opens. Pretty sure that was me getting lazy with hand placement. No follower breakage. Feeling better about the gun I come home and clean it. Take recoil assembly out and notice the outer spring is all bent up and the nut that holds the inner rod together is missing. So much for the better feeling. Hopefuly customer service will send me one. I do not have much faith in this gun at all. Was wanting it for a pocket carry back up. No feeling it.

I love ported guns.

Only a girly man would port a 9MM. Just sayin.

Rather than port my 40 and loose 50 fps. I think I will load my 40s for 50fps less.

Hey! I bought a ported barrel for my P9 while they were on sale and just stuck with carrying it like that. I WAS thinking about my Wife at the time, but she can't rack the Kahrs.

Now my Mag-na-ported P40 is going to be my main carry again. I was doing well with it and the Laserlyte training setup... even at 30 ft. When I DID miss, I could tell what I was doing wrong.

My Glock 40 is a G23C... the factory ported one. The Kahr ported barrel has no upward flash... thrown forward and away... not quite as much recoil reduction that way, either.

Hey firedude my guid rod assembly did the same thing with the outer spring dident lose the nut but the spring started bending and coiling over itself called kahr and got another assembly and so far so good kahrs cs has ben great for me so far but give it time for ur free parts took three weeks to get my replacment follower and three weeks for the guid rod aseembly they got alot going on so it takes time just have paintents if u need one now go on ebay there is someguy who has a guidrod ass and new slide lock spring for sale for 15 dollers unfortently the rod assembly is to short atleast was for me cause its the rout i took and i was just on there and seein he had more but i could use the front spring and u could use the nut off that assembly and it took like two days to get.it really does turn out to be a great firearm dont give up on it

will send u a new recoil assembly. if u can take a photo of it, send it to kahr attn: Jay. Those recoil assembly come fully assembly by the vendor to kahr. they are supposed to be locktited on but evidently urs was not. Notice thought the gun still functioned with this missing nut. Not sure I could loose faith ovber that missing nut, but again I ain't u either.

Is your ported barrel longer than the slide so that the gases have someplace to go?

Good advice jocky
I saw someone was able to put a nut on end of the inner recoil rod. I think they filed the nut down a bit but maybe they wouldn't need to.
