A Ruger Single Six would be a good choice. You don't need a DA for target practice (or anything really) or varminting, or point shooting or ..... Mine always is in my range bag.
A clinger. When guns are outlawed, only outlaws will have guns. Single Action .45 Colt (Sometimes improperly referred to by its alias as the .45 'Long' Colt or .45LC). Don't leave home without it. Ok.... the .44Spec is growing on me ... but the .45 Colt is still king.
