All of the brass came from ammo I reloaded.  10.3gr blue dot with 180 gr rainier plated hollow points.  G20 Gen 2 with a new storm lake barrel (tactical length).

Please confirm that these are merely "dings" from hitting the slide when being ejected and not the dreaded glock smile...  most of the brass has this, even with a lighter load..   

1) is this brass safe to re-use

2) assuming my hunch is right and this is NOT the dreaded smile that ruins brass, what do you recommend to eliminate these "dings".  New recoil spring>?

the brass cases were new starline.. I have fired them once.

It is not.  Search the forum and you will see examples.  Smiles are at the head of the brass...the bottom.

These are the normal dings and hits that occur during ejection.  Resize and load up.

Yes those brass are OK for re-use but you will want to pass-through size to recondition them prior to regular sizing and depriming...

Thanks to everyone.   Are these type dings possible to eliminate?  wondering if a new stronger recoil spring might help..

It can be eliminated if you know what is causing the problem.  The things that come to mind are;

1) The extractor as it is pulling the spent casing out of the chamber, is it hold the casing too tight against the breech, sort of trapping in position.  Usually this results in a tear at the case mouth or dents as the front of the casing is lifted by the next cartridge and jammed against the barrel hood when the slide is returning to battery.  Extractor may require cleaning and lubrication, could be wrong extractor or even damaged.  On a semiauto you do not want to drop a cartridge in the chamber and have the extractor try to jump over the case rim when the slide returns to battery.  As the feed from the magazine they slide under the extractor.

2) The ejector is struck by the spent casing as the slide travels rearward, it is kicked out from under the extractor.  A short stroke may not knock it off the extractor hook.  Too strong or binding recoil springs could be suspect.  Excessive slide speeds usually send the casing flying further than they should.  Some casings can strike the ejection port with enough force to cause dents, look for brass marking around the ejector port. Stronger recoil springs may help.

This has officially become my favorite shooting website.  THANKS!!!!  exactly what I was looking for...  Trying to learn a lot.

As a hint look at your slide for brass markings.  Generally you will see where the brass is hitting the slide as it goes through ejection.

Those are more like Glock (ejection) Love Bites
My G20 did the same thing to my Brass
It added just one more reason I hated the thing !

And yes, they ARE safe to reload and yes, they Resized / Fireformed out
So tell me again how Trump was worse then the 8 years before .... AND what came after HIM !

The Grip Angle stinks...Very unnatural
Their Stock; spongy / creepy Trigger really sucks
I'm definitely NOT a Poly Frame kinda Guy....and Make or Model
It's like hitting a Hardball while holding onto the fat end of a Whiffleball Bat
You can do it, but why would you when there are better Tools out there ?
I must admit though; They do make a GREAT Receiver for a MechTech CCU

But I can't fault anyone that likes theirs   8)
