So I came across a 7 1/2" BH last year with just a 45 ACP cylinder. For whatever reason at the time, I bought it. It still sits unused by me and I'm at a stand still as to what to do with it. Never really pay attention to the convertables. Is such a creature have much market interest? Almost considering simply sending it to Ruger for the missing 45LC cylinder since it a 7 1/2" model which I like. What are they charging for getting a cylinder supplied & fitted now? Did consider a 5 shot or such from Gallagher or the like but a whole new custom cylinder is just a bit cost prohibitive at the moment.
