Is your K hard on brass?

[tilefish]

Just curious to know if anyone else noticed their K series being rough on casings. I noticed a few casings seemed to have gouges or scratches in them after being ejected. I also noticed some brass debris starting to build up on the gun during break-in. Granted I did put over 400 rounds through it but I never noticed that with other guns. It really didn't even register with me until I was cleaning the gun and found a lot of brass debris inside. I was immediately annoyed with myself for not taking a closer look at the spent shells while I was shooting.
Gun seems fin, had zero issues and for all I know it could just be that the gun has a lot of hard, sharp edges inside and it will clear up after some more break-in.

Yeah, mine beats the crap out of my rounds. I stopped clearing it everyday because of how badly it was scratching up my bullets.

Get some denting on the .45's I've got, the 9... almost no denting. Over the years, I've seen far far worse. Seen .45 cases that pretty much were not practical to reload.

I shot 300 rounds thru a brand new k9 elite and was surprised at the amount of brass I sprayed out of it with crc upon cleaning.

IMO that brass looking stuff was in the gun when u got it and more than likely some machining debris left in the gun. That striker channel should be throughly cleaned and some take the entire slide down to do it, there is a great slide tutorial on the kahr tech section to help u to do that with ease. Once you get that striker channel spiffy clean, then from now on just use that little clean out hole on the bottom of your slide up by the breech face. Itwill keep that area clean without any more disassembly. I seriously doubt if that brass looking stuff is coming off the casing. The dent in the casings are normal. Kahrs manual shows and states that. Certainlymore round smooths everything out to but I wuld suggest a complete slide take down to be sure in ur own mind that all is well in that striker channel.

I try not to compare other guns to other guns. every gun has its own personality , get use dto it and ur gonna be OK. The K9 is in a class by itself as far as I am concerned. They are great guns..

No, it was the ammo. I detail stripped the entire slide prior to shooting it, I didn't just field strip it. I keep my guns operating room clean, inside and out. In fact I detail strip after every range session, I am kinda ocd like that.

Oh lord yes. My K40 puts a nasty dent in EVERY case--uniform as can be. Beats the heck out of me why this is considered okay or normal, but apparently folks are okay with this being 'just the way it is'. It's really something that should be corrected, to my mind.

I run 'em through the reloader just as though nothing's happened--I expect the case mouths may crack earlier than others, but the K isn't my main shooter so it doesn't see the 100s of rds per week the other 40 does. If I only get 30-40 reloads per case instead of the apparently unlimited number I'm used to, no big deal.

[Bug Splat]

I must have an odd duck. The brass my K40 spits out is perfect. No dents or dings.

[nexed]

yeah my K9 also is real touch on brass leaving a lot of them with big dents .

[jocko]

manual kinda shows dented brass, it is what it is. it is still reloadable and if u don't reload, why care??

[Bongo Boy]

There are a couple of reasons I'd prefer it be addressed and not simply brushed off as normal and totally okay--but let me first say this isn't a huge deal to me, nor a big source of annoyance.

The first is that, in my situation at least, the cases aren't 'just' dented--they also show multiple parallel serrations at the dented location. So, while this is very modest and I'm not talking deep gouges, still, it leaves marks in the brass that are permanent. These don't come out in the size/expand operations. So, now brass that you'd like to be smooth for assured operation isn't. These marks are also just the sort of thing that would lead to premature cracking, and again, another potential problem for smooth feeding and or extraction--depending on when the crack starts and when it's found.

The second reason is that it means the case is not being freely ejected. It's hanging up on, slammed into and bouncing off of some part of the weapon. While this may have never caused one single problem ever with any Kahr, the point is, the case is not being ejected clear of the gun in a way that intentionally minimizes risk of a poorly ejected case or a failure to clear the gun. It's not intentional, by-design operation--at least I don't THINK it is.

Now, if the designers set things up this way intentionally because they had a problem with cases coming straight back and hitting the operator or some other reason--then it's a completely different story entirely. You could argue that you don't like the way they chose to solve a problem--but that's a different beef.

I do see a perfect analogy here with software, however. We send product out the door with known, documented bugs we have no intention of fixing any time soon because they don't cause much of a problem and they don't impact sales or customer satisfaction. OTOH, I don't draw 'Excel' from my holster with my butt depending on it, either.
