All the Vaqueros have a transfer bar. They are not true replicas. All New Model Ruger single actions have a transfer bar.
The old model / 3-screw Ruger single actions are not replicas either, however they do not have a transfer bar.
The Italian replicas of the Colt SAA mostly do not have transfer bars, however they do have different forms of hammer blocks to pass drop tests.
The recently departed USFA single action had no transfer bar and was high quality.
The discontinued Colt Cowboy had a transfer bar. I do not recommend it.
And finally, the Colt Single Action Army is fundamentally the same gun as it was when introduced in 1873 and does not have a transfer bar.
For all traditional SA revolvers you MUST carry the gun with an empty chamber under the hammer (load 5 rounds only). NO EXCEPTIONS.
