Been shooting and enjoying new model Blackhawks for 30 years, and that's just the way they are made. I happen to like them.
If you want/need a gun that works like a Colt, BUY A COLT! or a clone.
Because if that's what you really want, get what makes you happy! Life's too short to waste being unhappy. And, if you are only planning on having one, get the one you really want, and don't worry about the price. You get more money with every paycheck, or at least, I do..
I've got a friend who has a safe full of colts (real colts and clones). He's kind of ...ehhh about rugers. I like the Rugers, and am kind of ..ehh about colts.
ITs your gun, and your money, but I just can't see trying to turn a ruger into a colt...he offered to sell me his Bisley today, would give me a great price...BUT all my single actions (10, currently) are new model Blackhawks, or Vaqueros (ok, a super single six and a new Vaquero also), and they all work the same way. Can't see changing to the colt operating system at this late date, not for me, anyway....
