shock buffers can put a gun out of time. heavier recoil springs will do what a shock buffer was designed to do without effecting the timing of the gun..:cheer2:Quote:

This is what the Technical Service Work Sheet stated;
First time - Replaced barrel, ejector, polished parts as needed. Lubed and test fired good.
Second time - Replaced slide, recoil spring, polished ejector. Lubed and test fired good.
With a new barrel, ejector and slide it's practically a new gun.
Thanks for the quick reply:) I hope it continues to work well for you .Quote:

I've made a magazine modification that seems to work in limited testing (125 flawless rounds compared to two jams in 25 with an unmodified mag). I really like the accuracy of my current slide/barrel/night sights combination and will probably just run the modified magazine another couple hundred rounds. If it proves reliable, I'll just stick with that; if not, I'll send it in.

Hopefully it works out. I know the feeling of frustration and would encourage you to stick with it until all the bugs are gone.Quote:

The note inside stated polished barrel, mags, extactor, replaced ejector, recoil spring. Lubed test fired good. It was not noted but the slide had the "notch" milled into it.
Went to the range today with 200rd of speer 230gr fmj and 50rds of speer 230 gold dots. Boy am I pissed! Not only does 20% plus of the cases strike me in the head still but now the gun had over a dozen failure to feed malfunctions which appear to be caused by the extractor not being tensioned or radiused properly. And of course the last round fired of the day ended with the same malfunction this all started with. The case was pulled through the feed lips of my newly purchased 6rd mag that I am sure is now out of tolerance. I could not get in touch with the service department today so I had to leave a message. No call back so far. How in the hell can I use this pistol to defend myself or others?
Man, sorry to hear about this, if the firearm is under warranty they should pick up the tab for shipping. Mine CW45 went out 2 times and it was on their dime. Basically is things are done right the first time they won't have to do it twice. If I had to send that gun in my dime, that would have cost about me $100.:eek:Quote:

I was able to run a further 80+ rounds through my CW45 today without incident using my modified magazines. That's about 175 total using the first one I modified; all without failure.Quote:

FWIW:
What I found was that the magazine lip on the ejector side was tipping the last round in the magazine slightly upward and slightly off the extractor before it got to the ejector in the ejection cycle. When this happens the case often does not clear the ejection port and gets driven back down into the magazine (as pictured earlier in this post) or barley ejects (more like falls or with a flat trajectory). With rounds still in the magazine, spent casing are (usually) held high enough by the following rounds that this would rarely happen.
To counter this, I decided to take some material off the magazine lip. I was pretty aggressive on the first magazine; I cycled a spent casing by hand and removed material until I felt the casing would stay in place long enough to hit the ejector. I took less off the next magazine and it seems to function fine. I imagine, with some patience and testing at different stages in the process, that even less material would need to be removed. The modified magazines hold the rounds securely and I've had no feed issues with them (I've dropped them a couple of times in the process with no lost rounds).

Modified magazines: the second one done is in the background; the modification on it closely follows the contour of the stock feed lip on the other side of the magazine:

I'm not saying this will work for all; it's just something to consider if your gun is malfunctioning as described in this thread. I guess, in this day and age, a disclaimer is warranted (sorry all): As with any modification, you proceed at your own risk; this is a "how I did it" post, not a "how it's done" article:yo::typing:

Short barrel .45's usually have more feeding problems than larger .45's. Even with the 1911 a government model will feed and eject much more reialably than an officers model.
Kahr called me today, the pistol should be here by tomorrow and I will give a range report after the weekend.
