P45 Marking Brass

[KahrArmed]

Hey, I have a question. I am noticing these marks on rounds I am firing through my P45. Any thoughts? The two Photos are the same piece of brass, just rotated. I am just wondering if it is anything i can fix or should be concerned about.

My P45 leaves some big chinks out of the rim too. I can feel them when I roll the case between my fingers. I also noticed a dent in the casing too.


Your post on my earlier thread mentioned a 500 round break in. Your observation was spot on. Approx 650 for me and the stovepipes and FTEs went away. My P40 was the same regarding rnd count to breakin. The manual is way off on this IMHO.


I'll watch this thread closely. I say if it feeds and ejects well, don't fix it if it aint broke.

Thanks Knkali. I have just started reloading, so I am hoping to not have to mess with the brass too much after using it, I mean, maybe having to file the rough spots down and such. Really would like to just fix it

Is every round chewed like that consistently or just one once in awhile?

[KahrArmed]

They seemed to be coming out fairly consistently, but i didn't notice it until i was just about done shooting, so I can't be exactly sure.

It really doesn't look like an extractor bite, too narrow, it's catching something on the way out.

I'd be tempted to smear a little prussian blue or some sort of marker around the ejection port and see where it's hitting.

Doubt you can replicate it cycling fast by hand with an empty case but I'd give it a try.

Prussian makes kind of a mess so not sure that would such a good idea in this case.

Have you tried slipping a case under the extractor with just the slide and seeing if it's snug or loose? Maybe it's just kicking the case out too quick or not quite quick enough.

[KahrArmed]

I will check the shell out with just the slide. Notice that the marks are very similar on both sides of the shell too.

Is there any difference between brands of ammo.?

[KahrArmed]

Here is a round in the slide behind the ejector Bawanna.

[KahrArmed]

Need me to get any closer? LOL

It is brand new brass that I loaded...

Interesting….this might be off the "chip" topic but when I'm looking at your
primer (obviously not the best angle for what I'm saying) I think I detect some
primer smear. I might be all wet, I/we've only been reloading give or take a year.

[KahrArmed]

what do you mean by primer smear?

[KahrArmed]

If you are referring to the drag outside the initial impact area of the striker, as I understand it that is the way primers tend to look with the P45.

Ok, I didn't know that the P45 did that. I have a PM9 and TP45, no P45.

Sometimes a primer smear can happen from barrel movement or a very hot
powder charge.
Maybe someone with more experience can chime in.

I'm always learning!
