Had an interesting specimen of rifling come into the lab the other day.

Six, right, polygonal?


Photos of the muzzle end of the barrel, test fire and cast of the barrel of the Sphinx SDP Compact pistol.

Hi Kirk, thanks for sharing. How was the firing pin, elliptical?

Circular firing pin aperture and hemispherical firing pin.
