This pistol is equipped with fixed notch-and-post sights, using a white-dot front and a white-outline rear for a clear, familiar Glock sight picture. Controls and external features noted on this example include a left-side slide stop lever, Glock-pattern takedown latch, and a squared trigger guard.
