Ok,
Here's a quick breakdown:
Ruger: Good, quality inexpensive Revolvers that are built like Tanks. The Blackhawks, and Vaqueros are damn nice guns.
Taurus: Hit and miss, nice looking, but finicky regarding reliability. These are like a combination of the old Colts and Rugers. Also cheapest in prices and quality.
USFA: Out "Colts" Colt. NICE guns, but spendy.
Uberti, Beretta, Cimarron: All the same guns, but they have some of the oddballs that are out there. Haven't had much trouble or experience with them.
Marlin rifles: Great rifles, but watch out for OAL in the .357 rifles. Also bring Loctite and Screwdrivers to matches. The screws sometimes work their way loose in prolonged firing.
Puma, EMF, Rossi: Nice rifles, no complaints.
Winchester rifles: NICE in the original configurations. Newer ones, I don't know much about.
Stoeger Shotgun: Best deal going in CAS, Nice reliable SXS shotguns.
Winchester 1897 shotguns.
Please, these are guns for gamers, nothing more. The Wild West was pretty much over when these pump actions came around.
