Unlike the Ruger Marks, they are hammer fired.
I have a MkII SS Bull, and Colt Woodsman MT. Never any problems with ammo or anything.I'd pass......I really don't like "em". BIL has one that had to have several repairs.......Plus it looks like an Elmer Fudd gun.........I'd get nice Buckmark iffen ya fancy a new .22.
I had a Ruger MK II with an Israeli military red dot scope on it. It out shot every 22 semi aito or revolver I have owned.Easy for me, just watch the video. But many complain about the Ruger MK2 and I have no problem with them.
