well, before i head to the school today i decide to give my new c9's ghost sight a shot. i brought along with 100rd and after 3rd mag of tuning, i pretty much get it right on the dot. in 15 feet i can pretty much get in within 3 inches. the ghost ring sight work much better for me than the regular sight. i still need to work on my grouping and i think i have flinch problem. if i take my time to sight i can't get within 3 inches to bull's eye but about one shot per mag i would have one way out of group. anyway, tonight i'll post up my target pix along with my c9...etc.
