Detailed Features 

 
The DA/SA action allows a heavier first pull from a decocked position, then lighter subsequent pulls, the same manual of arms as the full-size M9. The ambidextrous safety works for right- and left-handed shooters. Dovetail-mounted sights are adjustable for elevation and windage. The checkered aluminum grips offer a secure hold. The aluminum frame keeps weight at 26.08 oz, close enough to the steel-framed M9 to translate training to the larger caliber version.

The M9-22 is treated primarily as a training tool, and owners evaluate it on that basis. Its main appeal is the M9 form factor combined with .22 LR economy. Shooters who use or plan to use the full-size M9 can practice trigger control, manual of arms, and presentation at low cost per round.

Accuracy during target practice gets consistent praise. The DA/SA action is appreciated for its similarity to the service pistol. Build quality is described as solid and the pistol has a familiar, quality feel in hand.

Some owners note that the .22 LR caliber limits its role in self-defense scenarios, which is an expected trade-off for a training-oriented pistol. Reliability is generally good with quality ammunition, but like most .22 LR semi-autos, it can be pickier about ammunition than centerfire pistols. Some brands run better than others.
