I've used S&B ammo in 9mm and .45ACP. I was really happy with it in my Beretta, and can't recall ever having a jam. However, I was having some cycling problems with my Walther P99. I thought it was the Walther because it was new, but I tried the same ammo in my friend's Glock 17, and it had the same problems. No problems with the .45, btw.
Anyway, I'm not knocking the S&B because I think it's good ammo, however, you may want to try it out first to make sure it feeds well in your gun before you go out and buy a thousand rounds.
