Since I frankly just can't afford to shoot as much as I want to and buy .45ACP rounds..
I think I should pick up a conversion kit and shoot the heck outta that instead.
any thoughts on brands?

I have a Colt MarkIV series 80 ( if being a series 80 makes a difference )

also .. if anyone has one they don't want anymore....... I have no problems with a used kit

Thanks in advance!
