Just my opinion, understand that I am not 'touting' one brand of gun over another 'to each his own' as the saying goes.
Ok enough preamble:
I like the way the old style Vaquero fills my hand, note that I said 'old style, not old model, I believe that the old model has three screws, mine does not when I say old style I'm refering to the Vaqueros that preceeded the 'New Vaquero' which is built on a smaller frame than is mine and thus is said to be unsafe with loads listed as 'Ruger and Thomson Center loads' listed in many manuals. My Ruger has never shot the minimum or maximum load listed as I like to stay toward the middle of the powder spectrum. I would suggest that if you want a serviceable 'work' gun you look into purchasing an "OLd Style' Ruger Vaquero I have never had any problem with mine (new from Ruger through my FFL dealer) and have shot close to if not over one thousand rounds through it. You can usually find them in gun shops and/or shows that's where I got my last Vaquero(used) at a gun show and that one too has been trouble free thus far.
JUst my opinion , understand?
