Occasional shooter

I am just an occasional shooter, but still I have little trouble achieving better than a 2-inch grouping with a target at 50 yards, such as I’m doing with my father at a shooting range with this Springfield Armory 1911 handgun here chambered in 45 ACP.

My father is a regular shooter, at this distance his groupings are so tight that after a few rounds the target just has a big hole.
