I started off with a Springfield range officer, Sent it back to Springfield custom shop for some upgrades ended up with around 1700 in it. Ambi safety, ext mag release, SA mag well, checkering the frount strap. serrating rear of the slide. Dawson FO frount 4lb trigger, G10 grips and 2 tone finish , Looks good and runs great 500 + rounds with no stopages, I am sure it will shoot better and can, My eyes are old and by bodys fat and i have a flintch, but i can still shoot 6"plates at 20yds and zombies at 50yds
