As to that statement that there is no hammer block or transfer bar safety on an Uberti revolver, that is incorrect.
The guns must have a hammer block safety to be legally imported into the USA and they come one of two ways on Uberti revolvers.
One version uses the cylinder pin to act as a manual hammer block.
You can see if your revolver has this feature by pulling the cylinder pin and looking at the end that protrudes beneath the barrel.
If there are two grooves cut into the cylinder pin, your revolver has this safety.
By pushing the cylinder pin all the way into the frame until the last groove engages the cylinder pin lock or until the base screw on a blackpowder frame model will lock into this groove, the revolver is effectively hammer blocked and will not fire until the base pin is again pulled out far enough for the cylinder pin lock, or cylinder pin base screw, to engage the second groove.
The second hammer block version uses a tiny screw located on the left or right flat of the hammer to force a hammer block located in the front of the hammer into the up position.
This hammer block will also prevent the hammer from contacting a primer until the block is again turned into the lower position.
Both versions will allow the gun to be safely carried with six cartridges loaded
WHEN THE SAFETIES ARE CORRECTLY ENGAGED but both are incredibly inconvenient to actually use in a real world situation.
That said, it is still best to forget these safety features are even on the guns.
Only load these guns with five cartridges and lower the hammer on an empty chamber unless you plan on going to a gunfight armed with a single action.
