Yes is do! It is all specific to the particular glock firearm. On my 6th, and 3, bulged brass so bad, I would not reload it. The other 3 you would think have match grade chambers. The newest of the 3 with loose chambers was a G20SF 3rd Gen, and it was the worst! Threw the brass away immediately. Like I said it varies from firearm to firearm.
If guns kill people, then, I can blame my pencil on my spelling!
