The Walther P22Q is a compact .22 LR pistol with a Single/Double Action trigger and a 10+1 capacity. At 16 oz. and 6.50 inches overall with a 3.42-inch barrel, it's light and manageable. The tungsten gray/black finish gives it a more subdued look than most rimfire pistols in this class.

Features 

The interchangeable backstrap lets you size the grip to your hand, which matters more on a small pistol than a full-size one. Adjustable rear sights are genuinely useful on a .22 trainer — you can dial in the point of impact rather than compensating. The SA/DA system gives you a shorter, lighter pull for deliberate shots and a longer pull from a decocked hammer. Manual safety rounds out the control set. 
 
At 16 oz., the P22Q is one of the lighter options in its class. That works well for introductory use and extended range sessions where a heavier gun would cause fatigue. The .22 LR chambering keeps ammo costs down for volume practice.

The P22Q comes up regularly in conversations about .22 LR training pistols, and the reception is generally positive. Compact size and light weight get mentioned first by most owners, and the ergonomic grip is a common point of praise — particularly for shooters with smaller hands. The adjustable sights are noted as a practical advantage at the price point.

Reliability feedback is mostly good when shooting common bulk .22 LR loads, though some owners report feeding or ejection hiccups with certain ammunition brands. That's not unusual for .22 LR semi-autos, and most users find the issue resolves with ammo selection. The 10+1 capacity is considered adequate for plinking and casual range work.

The SA/DA trigger gets mixed reviews: some shooters like the flexibility, while others find the double-action pull heavier than expected for a rimfire gun. The main limitation owners point to is that it's a .22 LR — fine for training and target practice, but not a serious self-defense option compared to centerfire pistols.
