The Ruger Mark IV 22/45 Bull Barrel is a .22 LR semi-automatic pistol with a 5.5-inch bull barrel, a blued finish and a weight of 34.4 ounces. The polymer 22/45 grip frame has checkered synthetic panels and a serrated frontstrap, and it feeds from a 10+1 magazine. Two magazines are included, and the receiver is drilled and tapped for optic rails, with a fixed front sight and adjustable rear sight.

A heavier, longer bull barrel like this one points the pistol toward target shooting and training, where the accurate lock-up of a rimfire matters more than concealment. The one-button takedown makes cleaning quick without tools. Handgun buyers must be 21 or older, and rimfire cartridges are never legal for deer, so this pistol belongs on the range and in training rather than in the hunting kit.
