Hello, I have a Pietta 1851 conferderate navy 44.This gun shoots great! I've never shot "Cowboy action" before.But want to get into it this summer.I'm thinking of getting another one (w/ the shorter barrel 5-1/2").From what I read the "open top" revolvers are more accurrate and have better balance. But the the ones w/ a top strap are more durable.And I like the way the cylender can be changed on the top strap models.What do you guy's use?Should I get one of each or stick w/ the same?Thanks
