I got one of their Accusport SS Bisley Blackhawks in 45 Colt with a 5 inch barrel (actually, might be 5.5 inch, I have to check)..
It sure is sweet. Might be my favorite out of all the guns I have.
Looks a bit like this one, right?
Yep, I have one too, and you, sir, are a man of taste and refinement 
These revolvers were part of a run of 500 commissioned by the wholesaler AcuSport a few years back. Last year there was another batch made with cylinders for both .45 Colt and .45 ACP. Ruger has only officially cataloged the Bisleys in blued steel with 7.5″ barrels, though those limited runs sold out so fast that they really ought to reconsider.
yep,
And you too are a man of taste and refinement. My only disappointment is that when I traded for the gun (seriously, someone traded me this thing of beauty in exchange for a SAR-1 that cost me – new – about $200 ?!?!?!?!?) is that it didn’t come with the original box or paperwork. Would like to get one of those .45 ACP cylinders for it too. But it sure is sweet!
