Looks good, the 45 Super is a beast. I shot and loaded for it quite a bit in a G21 Gen4 with KKM 4 port barrel, most of the upper end loads needed the comp. Had the barrels freebore extended just enough so that I could load 45 Colt bullets (250-300gr) at the 1.26-1.27" OAL. Yours should shoot good, it was easy to get 800-900+ ft-lb loads with 250gr+ bullets.
