The Mark IV one-button takedown simplifies field stripping and reassembly. Its fixed-barrel, cylindrical-bolt straight blowback system enhances consistency with rimfire ammunition and is a defining feature of the Mark IV series.
The 4.40" cold hammer-forged bull barrel is threaded 1/2"-28 and capped with a factory thread protector. It uses six-groove rifling with a 1:16" right-hand twist, and the bore condition is excellent, matching the overall condition of the pistol.
Factory top and bottom Picatinny rails provide mounting surfaces for sights and accessories. Iron sights consist of a fixed front blade and a fully adjustable rear, offering precise elevation and windage adjustments.
The 22/45 polymer grip frame delivers the familiar 1911 grip angle, paired with checkered 1911-style grip panels for secure purchase. Controls include a push-button magazine release, ambidextrous manual safety, and a magazine disconnect. Capacity is listed at 11+1, and the pistol ships with two factory 10-round magazines.
The alloy steel receiver wears a blued finish that matches the overall appearance of the pistol. This example is a recent production piece from 2026, cataloged under Ruger part number 40149 with an MSRP of $689.00.
