I don't really have a preference for internal or external hammers at this point.
For my first handgun, I insisted on an external hammer and a manual safety. Now that I'm much more familiar with firearms and how they work, I am just as happy with a striker-fired pistol (internal hammer).
Because I have both striker-fired as well as external hammer-fired, I carry like so:
striker fired pistol = condition 1 (DAO pistols: round in chamber, hammer cocked)
external hammer fired pistol = condition 2 (SA/DA pistol: round in the chamber, hammer uncocked)
Ideally, I'd like to carry my SA/DA in Condition 1, but since I don't have to release a safety on the DAO pistols, I eliminate that motion in my SA/DA for CONSISTENCY OF MOTION across all carry pistols. God forbid that I carry the SA/DA and forget to drop the safety....
