Brand new bisley Blackhawk 44 special (Lipseys) with a very tight barrel/ cylinder gap. No feeler gauges, but just barely see light and piece of paper won't fit. Also seems hard to pull hammer back when cylinder starts to rotate. Haven't had big bore single action for while, maybe just don't remember how hard to cock. A little concerned about b/c gap though. Hate to pester Ruger again, just got my Redhawk back from them yesterday. Stiff hammer pull normal? I don't remember. Triker
