Caspian frame and slide, Kart barrel threaded and coned for bushingless slide. Yost/Harrison design gold line front sight. Adjustable rear. EGW Bambu safety. E2 hammer, sear disco. Chen MSH. Jon Huff Mesquite burl grips. Finished in brushed hard chrome over blue. I’m sure I missed a few details. Lots of fun to shoot and stays on target nicely.
