The Ruger 22/45 takes the best qualities of Ruger’s famed Ruger .22 caliber pistol and combines it with the legendary 1911 grip. One of the dominant features on many of the pistols is the Picatinny rail that lies across the top of the weapon and is designed to fit an optic.

The Ruger 22/45 is best outfitted with a lightweight, small optic that is designed for close range shooting—that is, a red dot sight. The optic itself needs to be rated for an actual handgun and not an airsoft or BB gun. The best optics will be able to resist round after round of firing without losing zero. The scope should enhance your abilities, your accuracy, and your ability to transition targets. A red dot should even make it easier to engage targets at longer range.
