Well, It's an interesting proposition.
Some things to think about. If your going to compete with the big boys in PPC, you'll need a heavy barrel revolver with a 6-7# DA trigger. An Aristocrat rib to finish it off.
You would need to spend the $1000 for that gun, probably another $1500 to get it competitive.
vs a used smith 64/65 gunsmithed to what you need.
If your talking distinguished, might be interesting.
I have no idea how you lighten the DA trigger on one. I believe they use coil springs.
