Smith & Wesson has just released the new M&P22 Magnum, a full-sized polymer-framed pistol chambered in .22 Mag.

This latest addition pistol brings more capacity, and more features to the M&P series. The internal hammer-fired design is paired with the Smith & Wesson’s unique Tempo gas-operated barrel system that keeps components locked in place until the bullet passes the gas port, increasing accuracy and performance. The rimfire .22 Mag. cartridge has a significantly thinner diameter than most centerfire cartridges, which allows the M&P22 Magnum to have a standard capacity magazine that holds thirty rounds. The pistol ships with two magazines and comes with a fiber optic front sight and a black notched rear sight. It has a flat-face trigger, and it is also optics-ready, allowing you to direct-mount most of the popular micro red dots available today. It is also fully ambidextrous, with a 4.35-inch stainless steel barrel that has an Armornite finish and has a Picatinny-style rail for mounting accessories.

“The M&P22 Magnum combines the best features of our internal hammer fire control system with the patented TEMPO barrel design, creating a smooth operating experience for the shooter. The .22 WMR is a versatile and field-savvy cartridge that has been a legacy among American shooters, hunters, and trappers for decades. Smith & Wesson is proud to offer a new pistol that further supports the use of this cartridge outdoors or on the range,” said John Myles, Senior Manager of New Products.

What Are Witness Marks?

I just became the proud owner of a single-shot pistol I found at the local gun shop. I intend to use it for target practice and maybe even hunting once I get good enough.
