I meant do GLOCKS. If so, which model and which brand/type of ammunition? I just ordered a CZ 75 Sp01 and I've been reading that some CZs can have troubles with certain ammo brands, mostly due to bullet length. I think of my Sigs and Glocks as indiscriminate eaters. Then again, I don't ever use steel or aluminum cased ammo, only FMJ or JHP with a brass jacket and plated bullet. I wouldn't like to own a 9mm that wouldn't eat any Blazer, Remington, Federal, Winchester WB, etc. that I could buy off the shelf, so long as it was brass. My neighbor, who is a very experienced handloader, told me that he replicated the data of lawman JHP and it wouldn't chamber in a Glock 17. This is somebody who is very well versed in reloading and who's opinion I take very seriously. So that brings me to the question...are Glocks picky about any kind of ammo? If so, what kind?
