To my eyes, RH 5026 4.2" with adjustable sights is perhaps more "match worthy" than GP100 1754 4.2" Match Champion with fiber optic? The 5026 is new to me (not yet shot) but seems overall similar other than heft of frame and cylinder for 44M and noted differences in sights...
Yeah, that's a great 44. I'd like to see some of the MC features like the contoured cylinder, target crown, slab sided barrel, and unique stippled wood grip on it though (well the Redhawk version of that grip).
Appearance is the only advantage in a slab sided barrel for a .44. Leave it round for a bit more forward weight and less muzzle flip. For me, the only match sight is a square top post, colored inserts red, white, gold, or night, OK for some applications.
I would really like to have a match champion on a Redhawk frame in .45
There are a number of possibilities, Redhawk frame in .45, .45acp, .44, .357
Current match champion in .22 would be great too!
