The Ruger Mark IV 22/45 Lite is a single-action semi-automatic pistol chambered in .22 LR, built on a lightweight polymer frame with a Gun Candy Pegasus Cerakote finish. The threaded barrel (1/2x28) makes suppressor attachment straightforward, and the adjustable rear sights let you set your zero without swapping components.

Detailed Features
The Mark IV platform introduced a one-button takedown that makes disassembly for cleaning significantly faster than the Mark II or III. The threaded barrel is ready for most standard 22 suppressors without adapters. Fixed front and adjustable rear sights cover most range distances without extra hardware. The ambidextrous manual safety works cleanly for both right- and left-handed shooters.
At 25 oz., this is among the lighter .22 pistol options, which matters during longer training sessions or when carrying at the range all day.
Usage
Well-suited for new shooters building fundamentals, .22 LR recoil is minimal and round cost is low. Equally useful for experienced shooters running suppressed or doing accuracy work. Not a primary home defense choice, but reliable and accurate enough for the role if needed.
