Rock Island Armory XT-22 Combo | 22LR/45ACP | 5″ | 51937

The Rock Island Armory XT-22 Standard Combo is a 1911-style semi-automatic pistol package that ships with both .22LR and .45 ACP slides and magazines to allow caliber interchangeability on a single steel frame. The package is finished in parkerized coating and includes a pinned 5″ barrel, low-profile dovetail front and rear sights, and checkered grips. For a compact red-dot that pairs well with this platform, consider a Holosun 507C or a similar sub‑compact reflex sight under $1000 for fast target acquisition on the 5″ slide.
