The optic ready slide is serrated for improved manipulation and supports mounted red dot systems without additional modification. This model incorporates interchangeable backstraps that allow shooters to tailor the grip to individual comfort and retention preferences. The flat face trigger provides a predictable break at a listed 5.80 pounds to support accuracy during rapid engagements. The steel GMB barrel and durable polymer framework together to ensure reliable function while maintaining a lightweight 1.27 pound overall weight.
