My friends and I do informal competition, shooting paper targets at 21 feet. I've been thinking about buying the Blackhawk Convertible 9mm/.357 stainless steel 5 1/2 inch barrel. Do you think I can expect any accuracy with the cheapest 9mm ammo? Yes, I realize that is a vague question. Maybe I should ask if there is anybody shooting theirs with whatever 9mm is cheap and available? Thanks, Bob
