Santa Fe County Sheriff Adan Mendoza confirmed that the firearm was an Italian-made Pietta Long Colt revolver. Most likely, an Uberti made replica.
It was an 1880 type Colt revolver so it would have had the first position hammer hold-off position (as in a carry situation). It also could not allow the hammer firing pin to strike unless the trigger was also pulled.
If it was a Pietta, how can it be an Uberti?
Aren’t those two competitors that make similar repro guns?
Thanks. Now that I know the model of the revolver I can properly evaluate Baldwin’s statement. I have the cap and ball version, which may have a similar hammer mechanism. I won’t know without a bit more research.
