Derr Precision

This custom built was the idea of the client. He wanted a pistol with no finish.

I selected a Caspian titanium frame and added a Caspian stainless slide in .45 caliber.  A Kart match barrel was fit to the slide along with a stainless EGW bushing. The stainless slide is equipped with a 10-8 “U” notch rear sigh and an XS “fat dot” tritium front for easy pick up in any lighting conditions. On the lower, a Smith and Alexander grip safety was hand fit for minimal gap. The hammer is STI and thumb safety is Ed Brown along with the slide stop. The grips are hand made from a block of carbon fiber by Cap in Ohio.
