Here is the best I can do to shine some light. I would hope off a sand bag now it would be a one hole gun, but the pic above looks pretty good. However shooting this unsupported it would not group.
Target on the left is my personal 1911 5 shots 25 yards unsupported.
Target on the right is the Colt before I worked on it. I was pretty steady that day. Same ammo and same effort 10 rounds.
(bottom target was some warm up shots from mine)
This is his gun after center target is at 15 yards 40 rounds not rapid fire but not slow fire either.
The targets on the outside were at 25 but I just couldn't get steady. Even so they are half size the original
It is much more accurate now then before with a lot less effort.
