The Walther P22 is a .22 LR semi-automatic pistol with a DA/SA trigger, a 3.42-inch barrel, and a 10+1 capacity. Weighing 15.1 oz, it is one of the lighter pistols in its category. The polymer frame includes interchangeable backstraps in multiple sizes, and the low-profile three-dot sighting system keeps the profile compact.

Detailed Features 

The polymer frame keeps weight to a minimum while holding up through normal use. Adjustable rear sights let shooters tune the point of impact for specific .22 loads, which can vary more in velocity than centerfire ammo. The interchangeable backstraps let the grip fit a wider range of hand sizes, a practical touch for a pistol often used in training contexts where multiple shooters may handle the same gun. 
 
The DA/SA trigger means the first shot from hammer-down requires a longer, heavier pull; subsequent shots are single-action and lighter. Some shooters treat this as a training asset; others just cock the hammer before the first shot. 
 

Usage Scenarios 

The P22 works well as a training pistol where .22 LR cost matters and recoil sensitivity is a concern. It also fills a plinking and range-fun role. Its small frame and light weight make it easy to carry in the field for small game or target work, though the 3.42-inch barrel limits effective range compared to longer-barreled .22 pistols.

Casual shooters and people new to pistols tend to like the P22. The .22 LR chambering keeps recoil minimal, the gun is easy to hold for extended sessions, and the interchangeable backstraps get specific praise for letting different hand sizes find a good fit.

Common praise themes: fun to shoot, low cost per round, easy to rack the slide. The DA/SA trigger is viewed as a training benefit by some; beginners can practice both pull weights without switching guns.

The criticisms are consistent. Some owners report feed and eject failures, particularly with bulk or lower-velocity .22 ammunition. The DA trigger pull in double-action mode is considered heavy by people accustomed to lighter triggers. A few long-term owners raise questions about the durability of plastic components under heavy use.

Self-defense comparisons to larger-caliber pistols are a recurring theme in critical feedback; most reviewers acknowledge the P22 is not optimized for that role. As a training gun or recreational shooter it holds up well, but buyers expecting a primary defense pistol tend to be disappointed.

It shoots well with varied ammunition, but the safety feels awkward for a longer thumb and the unusual magazine release takes practice.
