  The DA/SA action means the first shot can be fired with a longer double-action pull, with subsequent shots in single-action. The alloy frame keeps weight at 18.9 oz. The .22 LR chambering makes it economical for practice, and the 10+1 capacity is solid for the caliber class. One magazine is included.

The Bersa Thunder 22 in black/gold gets attention first for its appearance -- the gold-finished external parts on the matte black frame are distinctive and draw comments at the range. Buyers who wanted something visually different from standard black pistols are generally satisfied with how it looks in person.

For .22 LR training and plinking, owners report it works well with quality ammunition. Feeding sensitivity is the main reliability concern -- like many .22 pistols, it's more particular about ammunition than centerfire guns, and bulk or low-quality .22 LR occasionally causes issues. Running quality brass-cased ammunition eliminates most of the complaints.

The DA/SA trigger gets mixed reviews. The double-action pull is heavier than single-action, which affects first-shot accuracy for some owners. The single-action mode is described as acceptable. Grip size is noted as fitting medium hands well; smaller hands find it a stretch. Overall the Thunder 22 is recommended as a low-cost practice pistol for those who want DA/SA trigger training at .22 LR prices.
