Features 

 
The double/single-action mechanism lets you choose between a longer DA pull for quick fire or cocking the exposed hammer for a lighter SA shot. The rubber grip with finger grooves keeps the gun steady during extended sessions without much fatigue. The adjustable rear sight allows windage and elevation changes to dial in at different distances. Blued steel holds up reasonably well against light outdoor use, though it requires more maintenance than stainless in wet conditions. 
 

Use Cases 

 
The AL22 works well for casual range days, small game hunting, and basic training. The .22 WMR cartridge hits harder than standard .22 LR, giving it some practical utility against small pests while keeping recoil mild. The adjustable rear sight and fixed ramp front are adequate for the distances this caliber is typically used at.

Owners of the Rock Island AL22 Blued Revolver tend to focus on a few consistent themes.

The price comes up as the main draw — it is one of the more affordable .22 WMR revolvers available, and most buyers feel the value holds up. The low recoil of the .22 WMR cartridge is frequently mentioned as a positive, particularly for training or extended range sessions. Accuracy at typical distances is generally reported as good, and the lightweight build gets praised for ease of carry.

The negatives are also fairly consistent. Trigger pull is the most common complaint — the DA pull in particular can feel heavier or less smooth than expected, which affects shooting enjoyment for some users. A few reviewers flag limited parts and accessory availability as a potential long-term concern. The 8-round capacity is fine for most uses but draws comparisons to other revolvers chambered in similar calibers. Sights and grip ergonomics occasionally get mentioned as areas where improvement would be welcome. There are also scattered reports of misfires with certain ammunition, which leads to discussions about compatible loads.

The AL22 reads as a serviceable entry-level .22 WMR revolver that covers the basics without anything noteworthy standing out in either direction.
