P45 Marking Brass

Nice pictures! If that was a new case, then the marks must be made as the round comes out of the magazine. Look for a burr on the lips of your mag. Feel the inside of the mag lips with your finger to see if there is a rough spot. The marks are getting there before the round is fired. IMO

Makes perfect sense to me--especially since he said there were matching marks on the other side.

Thanks KahrArmed, I learned something!

I am using a modified Kimber Officer's mag, so i will take a close look at it

Using that mag might be causing the case to hit too low on the feed ramp and forcing the round up into the leading edge of the mag lips and causing the marks. To test if that is it, go back to the original Kahr mags and see if you still get the marks.

Okay, here is the mag from a couple different angles. I see your recommendation Ikeo, obviously can't check that out in the garage If anyone sees any other problems with the mag, let me know.

We're close to April 1st, but we're not there yet.

FWIW I am getting this sort of thing with Kahr mags. When I hand rack I get a slight feel of where the extractor is but definitely different(more) when fired.


I am gonna watch thread still but think I'll take Jockos advice and "shoot it like I stole it." I think that is what he says. However reloading could be a trouble with this situation.

How smooth can you insert brass into the extractor from the bottom of the slide?

My PM40 extractor would dig into the brass quite a bit before I worked on it.

Mine did the exact same thing for the first few hundred rounds. I figured it was the sharp edge of the ejector pushing out the spent case. The P45 has the ejector with the squared edges, so it digs into the cases a bit during break in. 1,600 rounds now, no more chunks out of the cases and brass in not distorted or misshapen.
This is a video I made in response to a fellow Kahr owner whose cam was contacting the magazine:

I show this only because the ejector is clearly visible.

Here it is firing 27 rounds with no hiccups:

No more problems, no complaints. It took a lot of sanding, polishing and finding the root cause of my problems before it was finally able to fire and cycle without incident.

It appears to me that your mag modification needs to be "smoothed up".

Use a fine file, or sandpaper, to deburr the edges of the mag. You don't want to remove metal, just "dull" the edges. Sometimes even a new mag needs to be deburred.

Try it, it can't hurt!

Just my 2 bits worth
