Needing to calm before the storm....

Yup I bought in to the Kimber hype again! Bought my 3rd Kimber in a 4in. round butt 9mm Aegis. Absolutely loving it....

But I also like my Stainless ii in the 5in 45.... but now lil worried, will get into that in min. and my first one, was actually bought as a back up and main shooter for my wife. in a stainless CT micro9...

How where I'm getting flustered... The Micro9 I just cant shoot, all my other handguns I shoot fine or my fine which I know, but even a 2 yards the micro 9 shoots 4in low, and with someone watching to see if I'm jerking or what....so guess it back to the wife only, but that's ok....

But not ok with my stainless ii 45... sent it back to Kimber with what I see as a cracked frame... Judge for yourself.... But also got a email today from Kimber saying that is tool marks not a crack?!?!?

I was a machinist for 20 years, and if the one I see is a tool mark that guy need to taught to mill better... Its not cracked thru the frame but ..

what would you do?!?

Well, I can only tell you what I did.

Back when the hairy mammoth ruled the earth, I bough the then new SW 639. It shot like a dream. I took it home and cleaned it, and I kept catching the rag on something. There was a little hair-line crack down the center of the rear portion of the bottom of the slide.

Since it was new and under warranty, I sent it back. I got a call from an SW supervisor who told me it was good we caught it. Sooner or later the slide would have broken cleanly in half and the firing pin would have lodged in my forehead as the broken slide flew backward upon recoil.

If your receiver has a crack, I'd send that picture back to Yonkers and ask them what to do. MY guess is that they'll want the gun back.

Tourist, looks like the OP already sent the gun back. For what it’s worth it doesn’t look like a crack in the pictures to me. If Kimber has looked at it, I’m certain they wouldn’t tell you it didn’t have a crack if in fact it did. Did you ask Kimber if there was anything they could do to smooth out the tool mark for you?

I am sure that you, an experienced shop technician, know it is not a crack. However, it is a stress riser. You have documented the abnormality with Kimber. Inspect it each time you break it down.

It's an internal mark, and the machining in that area looks pretty rough to begin with. Really, it's an off the rack gun and there should be little expectation of a beautiful finish on the internal parts. That area doesn't do anything anyway; you could cut it off with a hacksaw and your gun would still run flawlessly. Let it go, shoot your gun, be happy.

I really can't add anything except it doesn't look like a crack to me, but I would keep an eye on it after it's been shot for a while.

My issue was that I'm not a metallurgist. To me, how can I tell if a tool mark is okay, but a crack is dangerous?

It is ain't supposed to be there, a phone call is cheap insurance.

The issue is the location of the flaw. A crack can still form from the edge of the tool cut. I think Rusty is saying a crack in that part of the frame will not cause a danger.
I am not a metallurgist either.

Just the dustcover end-no stress to speak of-also looks like a tool mark.
