Smith & Wesson M&P 22X .22 LR | 4.1in Threaded | MFG# 14312

The Smith & Wesson M&P 22X is a full-size, optics-ready rimfire pistol built to combine economical .22 LR shooting with full-size ergonomics. It features a 4.1 inch threaded stainless barrel with an Armornite finish, an anodized optic-cut slide, and a slim textured polymer grip designed for extended sessions and consistent handling. The pistol ships with two 20-round magazines and includes a 1/2×28 threaded adapter and wrench in the box.

For optics, the pistol accepts SHIELD/RMSc footprint red dots; a Shield RMSc footprint red-dot (for example, a Shield RMSc model) is a practical option that will mount directly and is typically priced well under $1000. Typical uses for this pistol include range plinking and rimfire training, and it is also suitable for informal rimfire competition where low-recoil, repeatable handling is valued.
