Dependable performance in a smaller size Stoeger developed this sub-compact version of the STR-9 with concealed carry in mind. It has all the power, reliability, performance and safety features that are standard in STR-9 line, and delivers them in a more compact version that is optimized for ever-day carry. Each STR-9 comes outfitted with a three-dot sight system featuring snag-resistant edges to ensure smooth draws and holstering. Among the STR-9's integrated safety features is a tactile loaded-chamber indicator on the top of the receiver that automatically raises when a round is chambered. This allows the user to confirm the presence of a round in the chamber by touch in low light. Three interchangeable backstraps (small, medium, and large) offer a custom fit to get you on target quickly.
