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.
