Owners of the STR-9 Thinline point to its slim grip profile as the defining selling point, making it easier to conceal than full-width striker pistols in this caliber. Shooters with smaller hands or those who prioritize concealment over round count tend to prefer the thinline frame.

The 14/16 round capacity options give buyers some flexibility, though some owners note that the thinline grip reduces the feel of control compared to wider-framed alternatives. The trigger gets mixed reviews, with some finding it smooth out of the box and others describing a heavier pull that benefits from break-in.

Value is generally considered a strength of the STR-9 Thinline relative to its price tier, though a portion of buyers report needing a break-in period before reliability settles. Overall build quality impressions are positive, with the polymer frame considered solid for the category.
