My Virginian Dragoon - if that's what you refer to when you say "Virginians", has an inertial firing pin.
It's perfectly safe to carry it full up 6.
The Virginan and the Virginian Dragoon are entirely two different revovlvers, both from Interarms. The Virginian was made in Switzerland by Hammerli, while the Dragoon was made in Alexandria, Virginia by Interarms.
The Virginian was a very close copy of the Colt Single Action, while the Dragoon was more akin to a Ruger Super Blackhawk, larger and heavier, and a very robust revovler.
