But that was after 2 FBI agents were killed and 5 wounded by the two bad guys. One of whom being armed only with a sawed off shotgun loaded with bird shot. Most of the damage was done by one of the bad guys with a semi auto rifle. The FBI agent who ended the fight with his revolver thought he was dying and charged in to end the fight at point blank range. Incredibly brave but perhaps not a tactic one would choose if they had more rounds available. The shootout was a major reason why the FBI completely ditched the last of their revolvers and started arming all their agents with semi auto pistols and long arms.
The revolver is a good idea for someone who can’t manipulate the slide on a semi auto. Though the long heavy double action trigger could be equally hard to control for someone with finger strength issues. It also takes a lot more practice to learn to shoot accurately even for someone with strong fingers and reloads are very slow and complicated as one of the FBI agents found out in that shootout.
