The Gaucho, Beretta Stampede/Stampede Marshall and Ruger New Vaquero are all "close size/feel clones of the SAA but with transfer bars".
Of the three the NewVaq is the least authentic because you reload with the hammer fully down - just open the loading gate and go. The Beretta and Taurus load on the half-cock. The Ruger system is arguably "better" in that there's less steps and it's fractionally safer because the hammer is DOWN fully during the reload.
In the New Vaq and 50th Anniversary 357 Blackhawk, Ruger fixed the problem with the Old Vaq (and other New Model large-frame SAs) where the cylinder bores didn't line up with the loading gate on each "click".
The worst thing about the New Vaq is the fake-color-case. Ruger's newest chemical process (introduced somewhere in the Old Vaq era) at least no longer *attracts* rust. But on my gun, while it's not rusting it is wearing to a plain gray versus mottled on places my finger rests along the right lower frame. It's not "bad", I just don't like fake anything. There's been a distributor run of all-blue with white micarta grips that looks sharp and Ruger didn't DARE desecrate the Wayne gun with fake-case. Or there's stainless, or worst case the fake-case can be refinished later.
There have been quality control issues reported on the forums on the Gaucho. Enough so that I wouldn't buy one. The Beretta is not getting negatives so if you need that half-cock, go there.
