Vinny -- I'm thinking co-witness with a red dot and comp on a P-07 would be absolutely perfect for what you want to do.
I'm also thinking a red dot on a 9mm Sugru'ed and JB-Welded CGW part enhanced 5" P-10L(?) striker plasic gun would be the absolutely perfect, most irritating pistol I could shoot in a bullseye match with all my old school custom 1911 bullseye shooter buddies.
They couldn't believe my P-09 (or the P-07) and I think a P-10L would cause considerable consternation.
Not saying my scores would top the 97B"E" in a bullseye match, just that the plastic gun scores would be closer to a "real bullseye gun" than most people would ever expect.
This is fun.
