To me it`s Rugers only because of the durability and price. That also goes for my off-topic big-game rifle.
My first singleaction was a SuperBlackhawk. Before CAS, the fun part was heavy loads. When I started with CAS I used my Super for a while, then changed to a Schofield. But my hands ain`t to big, so i didn`t like the grip for duelistshooting. Then I changed to 5\5 Vaqueros, and hopefully that will be my last trade.
Once in a while I shoot cap & ball, and then I find the Remington 1858 very reliable and accurate.
