Bent lip on ejected brass, and overall break in issues?

Have fun, I think you will get the reliability that you were expecting tomorrow.

Here is mine, take a look.

This post reminded me of something. The grip screws work loose, take a screwdriver along to tighten them if they do. I put lock tite on mine.

A lot of that will clear up as breakin continues. Just use factory full power ammo in the beginning. You have a good pistol. My cm45 had very similar issues in the beginning but its all good now.

Muggsy, my Glocks don't do it.

My glock 19 will do a lot of ugly things if you dont baby it.

Now my 30S is flawless since day one. I use the 19 to practice and the 30S for business.

Not all of them do.

On page 23 of the Kahr MK40 Owners Manual it states that dented case mouths are caused by the brass striking the lower side of the ejection port and this is to be considered as normal. There is no need to contact Kahr for service. It also discusses primer smear as being a normal. If any of you ever took the time to read the owners manual you might learn something about your gun. That notch in the left front frame rail is supposed to be there, too.

Finally had a chance to get to a range yesterday. Put another 100 through it with only 1 failure to fire. The dented brass still weirds me out (the range officers assumed extractor but had never seen something like this happen.) Glad to read that it's pretty standard, though. I collect my brass as I'd like to eventually reload, so I have another question: Will continual use reduce the dramatic denting, as some cases are so warped I couldn't imagine they could be safely resized. Thanks again for all the help.

The bent brass is normal and fine to reload. I reload it all the time. Sometimes I need to "push" the bent side out a little using something like needle nose pliers, from inside the case, before forming.

I've had much worse than these....

That's great to hear. I've quickly noticed I'm a much better shot with the MK9 over my FNS9 (the sights feel more natural to me) and it's a pleasure to carry. Nice to see things are going to be fine.
