Shoot it, if the brass comes out without too much damage, don't worry so much.
Good buy. Glocks are great all around beaters and they eat anything you put in them.

I wouldn't worry about it at all...In my years in Michigan...I put almost 10,000rds thorugh a G22 with ZERO issues...and STILL ZERO issues whatsoever! And with the holster wear from thousands of draws/presentations...it looks even better! (Not having to pay for the ammo is such a great benefit!)
