My Glock 23 is on the way. I just brought a 1,000 once fired brass. Got some bullets. Some powder and primers. Now I see people mentioning that you shouldn't shoot reloads in a Glock because of an "unsupported chamber". This will be a Gen 3 or Gen 4. Don't know what my FFL ended up ordering yet. So what is the truth: are reloads taboo in a newer Glock? Need to know.... Tim
