Looking for recommendations on a first black powder revolver. Not my first firearm. I have other cartridge and black powder arms already but don't have a pistol that shoots cap and ball. I'm thinking .36 caliber is what I would like best but might be convinced otherwise. I seem to like the looks of the ones in the 5 to 6 inch barrel range or so. Any reason I should only consider a longer 7 1/2" barrel? I don't want a gun that is super heavy. Function and reliability is the first priority. Fit and finish less so but still don't want a hunk of manure either. Recommendations on places to buy? Leary of Midway USA and the no returns. Would probably pay a little extra and hopefully have that option if I got one that didn't function out of the box. I don't want to tune my first gun much. Please share thoughts and opinions please!
