The Stoeger STR-9 Mid-Size is a striker-fired 9mm semi-automatic pistol built on a mid-sized polymer frame. It pairs a 4.17-inch barrel with a 10+1 magazine capacity and interchangeable backstraps, aiming to deliver full-size shooting characteristics in a more carry-friendly package. This example wears an FDE/Tan distressed finish over the frame and slide.

Owners of the STR-9 line often describe it as a reliable value pistol, with the trigger and slide-to-frame fit feeling tighter than the price point would suggest. Some new shooters mention a break-in period is helpful before the gun runs completely smooth.

Ergonomics get generally positive feedback, with the mid-size grip and interchangeable backstraps letting a wider range of hand sizes find a comfortable hold. A few carriers note the pistol prints slightly more than a true subcompact given its frame size, which is expected for a gun built with a fuller grip.

On value, the STR-9 is frequently compared favorably to pricier striker-fired 9mm pistols, and the distressed FDE finish is popular among buyers who want a worn-in look out of the box. Aftermarket holster support has grown as the platform has become more common.
