I'm going to recommend a different path. Back many years ago I acquired a pair of Series 70 Colts that had been customized by John Giles, an old time pistolsmith, as "hard ball" guns for competition. They have adjustable sights and a nice crisp 4 pound trigger pull. I remember on a PPC course cutting the X-ring at 7 yards.
There were a number of famous pistolsmiths back in the 1940s-1970s, men like John Giles, Jim Clark, Austin Behlert and Bob Chow who supplied competition guns like this. As the bullseye shooters of those eras have retired or passed on, these guns are starting to come on the market at reasonable prices considering the amount of work done. One of these guns may be the ticket.
