Had my G21 from 1990...there abouts. Shot about 5000+ 220 gr lead semiwadcutters thru it...target loads and never had a problem. Now that I am in Miami, I here that GLOCK says NOT to use lead! Strange....never had a problem. So I got a Lone Wolf extended and ported barrel for it. The barrel finally broke in after about 400 rds. I was shooting 200gr lead round nose over 5.8gr of 231. Shoots great but super loud! Anyone else using lead in their GLOCKS?
All polygonal barrels say not to use lead, they will cause alot more fouling in a polygonal (hexagonal in Glock) barrel. There are countless people who do it anyway without problems though. Also, you can always just use a wolf barrel in your glock when shooting lead to be safe.
