Default glock brass

i thought i remember hearing something along the lines that glocks tend to put a wierd dent in the casing when ejected making it hard, or non reloadable. is this still an issue? or is it rare?

It can be more pronounced with different calibers. My 9mm Glocks don't seem to leave a pronounced bulge. Many of the .40 cals do.

This can come from an area of teh chamber that isn't supported in that area that the case wall transitions to teh case head which is solid brass. this could cause stretching and compressin in that "web" area that could cause stress and weaken the cases there over time.

I've heard that the cases are not reload able because the non supported chamber causes case distortion.

I have shot and reloaded brass from Glocks in all kinds of calibers for 13 years. The only issue I have is my after market Lone Wolf barrel notches the case mouth and sometimes it is bad enough to split the mouth.

I have zero reloading issues with factory barrels.

I think the idea is that the unsupported chamber will work the brass more and the brass should fail faster. Never reloaded for glock, so I don't know, but the range brass that I find from an unsupported chamber looks bad.

It might have been a problem with gen 1 glocks. It's not a problem now. Kinda of like glock leg, once it gets on the Internet it never dies

"Glock bulge" is a distorted area near the base of the brass where the feed ramp leaves the case unsupported. It can be corrected with a Case Pro, Case Master or Bulge Master. If going to be shot in the same barrel, it rarely causes problems

I purchased a Glock 23 in the early 90s,this was my first dealings with the "Glock Bulge" where the unsupported part of the case develops a slight outward bulge at the base. During the reloading process is where I noticed the problem,with my first set of dies(Dillon) the resizing die wouldn't take the bulge out. I started using RCBS dies that did take the bulge out out of the cases,I also purchased a cartridge gauge to check my cases after the resizing process before,continuing reloading a bulged case.

Just recently I started reloading the 9mm para,I had a bunch a range brass saved over the years.
I haven't had any problems with a Glock Bulge in the 9mm cases,i'm sure a lot of it was shot through Glocks with the rectangular firing pin mark on the spent primers,and i'm using Dillon dies for the 9mm para...So far so good?
