The Grayguns "Lockwood" slide is cut from stainless steel and finished in stainless, with aggressive square/checkered serrations for confident manipulation. Top and side lightening windows reduce slide mass, while anti-glare top checkering helps manage sighting surfaces. The slide is optics cut.

The 4.9 in stainless, non-threaded barrel complements the striker-fired action. A skeletonized curved trigger delivers a crisp, consistent pull. The push-button magazine release is configured on the left side.
