I have shot more than 5K rounds of steel cased ammo through my G43 - mostly Russian made and some US made - with no hiccup. I have also shot more rounds of aluminum cased ammo through the same gun and through other Glocks I own. They are in fact very effective bullet launchers!Not only will the Glock eat el crapo ammo - it will do so trouble free without any jams, cleaning or special attention. It is a supreme bullet launcher.
I carry Glocks because they are super durable and reliable rounds after rounds after rounds…. I also like Glocks because they are stupid easy to maintain.
