Overview

This semi-automatic 9mm pistol is built for shooters who want a compact, duty-style handgun with adaptable carry and range use in mind. Its striker-fired system, 4.0-inch barrel, and lightweight polymer frame with embedded steel chassis keep the profile manageable, while the fully ambidextrous controls and interchangeable backstraps help tailor the fit. The flared magwell, fixed three-dot sights, and accessory rail support practical handling and setup, and the optics-ready slide on OR models adds flexibility for miniature red dot sights. Condition is noted as slight holster wear, so buyers should review the photos for cosmetic details.

  • Factory-milled slide on OR models supports miniature red dot sights with included plates.
  • Four interchangeable backstraps help tailor grip fit and palm swell.

Considerations & Trade-offs

  • Factory-milled optics-ready capability applies to OR models, so confirm the exact configuration before planning a red-dot setup.
  • The 17+1 and 15+1 magazine capacities are useful, but they also mean magazine selection and carry setup should be matched to the intended use.
  • At 21.6 ounces unloaded with a polymer frame and steel chassis, it is relatively light for a full-size 9mm, which can be a consideration if you prefer more mass in hand.
  • Condition is listed as slight holster wear, so this is not a new-in-box example and should be evaluated accordingly.
