So I got my Glock 20sf and so far only have practice Ammo (American Eagle). I've been doing research on different Ammo loads and I get a lot of people complaining about Bulged Brass etc. The general thought is Glock really messed up with the Barrels by not giving too much case support and yadda yadda. My new Glock 20SF seems to support the case fairly well so I'm not sure if it was something was fixed or what? But I'd like to be on the safe side. Do I really need to get an aftermarket barrel to be on the safe side or should I just shot to full power stuff and check my brass?
