First Look: Smith & Wesson M&P22 Magnum With TEMPO Barrel System

Smith & Wesson has just released the next gun that uses its TEMPO barrel system, the M&P22 Magnum in .22 WMR.

Smith & Wesson debuted its new TEMPO barrel system at SHOT 2023 when it announced the M&P 5.7, but another pistol was just released that will utilize it as well. Called the M&P22 Magnum, it’s chambered for .22 WMR and features a 30-round capacity.


The M&P22 Magnum has a full-size polymer frame, a 4.35-inch stainless steel barrel and an internal hammer-fired design. The TEMPO gas-operated barrel system doesn’t allow the gun to unlock until the bullet has passed the gas port, theoretically improving performance and reliability. Furthermore, it sports an impressive capacity of 30 rounds and ships with two magazines.


John Myles, Senior Manager of New Products at Smith & Wesson, said this about the new pistol:

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.


Other notable features include its green fiber optic front sight, optics-ready slide and accessory rail. It also has an ambidextrous slide stop and thumb safety as well as a flat-faced trigger. The M&P22 Magnum has an MSRP of $649 and it’s available now.
