Mine with factory bbl, puts 5 rounds in a 2" dot at 20 and at 25 yds one was a tad low but I called that one low.
So 2" out of a factory pistol at 25 yds I will be VERY happy with all day long.
Enjoy your new rebuilt gun. Half the fun is making them the way you want them!!!
Good fortune with it! Hoping lots of 1st places for you!
