Shy of the Ruger Mk-I and II and 22/45 .22 series of target guns I know of no one in my arena for work , competition and or fellow IDPA shooters that uses a ruger semi-automatic. Their Blackhawks, Vaqueros, Bisley’s and Redhawk’s are AWESOME handguns and I own many of those. Just never liked the fit and finish of the ruger semi-auto’s mentioned. Even the small pocket pistol designs stolen from others......Bet Bill Ruger wouldn’t have approved that were he still at the helm.
Rugers have varied quite a bit in finish but fit has always been first rate. I did have an early new model Super Blackhawk which had a very fine finish. Most of my .45 and .357 Blackhawks had mediocre finishes but still had that near perfect fit.
Ironically, all three guns I tossed overboard before my 2 hour Mexican visit were Rugers. A .22 Mk 1, a SS mini-14, and a SS .357. Now I own no rugers, and don’t plan to.
