I've just this past week received 500 rounds of .45 Super brass from Starline, most of which I'll form into .400 Cor-bon. I've e-mailed Fernando, at Triton, to get his opinion as to whether my factory Glock 21 barrel, with heavier recoil spring, will handle .45 Super loads. I haven't heard from him yet, but he's pretty good about responding to e-mail.
You might want to e-mail him. Check out the Triton website and you'll find his e-mail address.
