Sig P220 question

[sigster]

Have always enjoyed handguns but was always into wheel guns until now. I purchased a used (2002) sig p220 LEO tradein. Being my first semi-auto handgun I have nothing to compare it to but after a couple mags I love it! Nice crisp trigger, even in da.

My concern is after shooting, I was picking up the brass and noticed that every one had a small dent/crease about midway. I assumed it was from hitting the port when ejecting as it was throwing them about 10-12'.
Is this normal or is something up I need to have looked at.

A picture would be helpful. Semis do beat up brass though.

[sigster]

Of all the dumb luck! I think I tossed the brass after seeing the dent, guess I'll just have to shoot that thing again tomorrow and take some pictures.

I shot a few more mags today in the rain no less but it sure was fun!
The first picture is the brass showing the dents
Second picture is the 220 and mags and my 1930's case pre-tactical knife
Last picture is a 9" target shot at 15yds. Now before everybody starts asking about these targets, they are private stock and not available fror sale.

nice case, nice sig.

i can see the dents in the spent rounds. im curious as to how that happened as well.

good luck on finding an answer.

Might be the way you are loading the rounds into the magazine, putting too much pressure on the round to load the next one, try loading only one round into the mag, rack the slide to chamber it, then again to eject and look for the dent, if its not there do it again with one round only and fire it and see if you have a dent. That will tell you if its the gun doing it. I had this happen to me and it was how I was loading the mags.

Hope this helps

The good news is that those kind of dents won't harm anything. You could even reload them just fine.

Might be the way you are loading the rounds into the magazine...

Almost certainly not. Brass forms to the inside of the chamber under those kinds of pressures. Research fire forming brass for wildcat cartridges. This definitely happens after the round has been fired. Besides, the area of the case which is being dented should have bullet supporting it.

While the ejection forces are strong, I don't see them causing that dent from "flinging" the brass into something on the gun. Not saying it's impossible, but seem improbable to me. If the brass was stove piping or otherwise hitting the gun you'd notice brass marks and it'd likely have jamming issues. I've seen similar dents from the brass falling on ground and hitting something. For example, large gravel, the concrete edge of the shoot line, etc. What's your range like? Anything around that the brass is hitting?

Well I call in out in the backyard down by the creek but I like the way "range" rolls of the tongue.

All grass where I'm shooting so it has to be something on the gun causing it.

I'll try again tomorrow with one at a time and see what I get unfired and then fired.

Thanks!

Is this normal or is something up I need to have looked at.

It is not "normal", but it is not uncommon...Google "dented .45 brass". It also doesn't appear to be unique to one brand of .45. My Colt does it despite a modified ejection port. Function is not affected, and it drops hot brass on my son-in-laws head, so I haven't felt the need to have it "fixed".

[sigster]

After googling, it does seem to be pretty common. I'm not going to worry about it unless it gets worse.

Thanks for the help everybody.
