It is a Bianchi Metallic division (NRA Action Pistol) gun that takes advantage of all the rules. I built it on a Fosters frame, Caspian slide with an STI TruBor blank 9mm barrel. I wanted to run a 6.25" barrel with an 8.5" sight radius, yet have a lighter 5" slide. The front sight is from Clarks, sitting in a European style dovetail (along bore, not sideways). The sight sits on the end of the TruBor blank, so it is similar to a sight tracker and gives the extended sight radius without the weight of using a 6" slide. Plus, it is a true 6.20" length barrel which I felt was better than putting a fake comp on a 5" or 6" barrel. Additionally, the heavy (HEAVY) barrel reduces slide velocity. Initially, the slide wouldn't even open after firing a +P round. Barely opened after lightening the slide. Then I started taking weight off the barrel blank until the slide "just" functioned and locked open on empty. Very soft shooting, without being sluggish or slow.
The rear sight (Shifty Sight) is my own design that shifts Right and Left for the mover event. It returns to center so there is no need to rezero after shooting the mover. The lead length is adjustable for different bullet weights/speeds and barrel lengths. Once set, the sight unlocks, shifts to the stop (right or left), then locks in place. It works great and it probably the best thing I've designed so far, mainly because it is so simple. I can't believe it hadn't been done before. I tested this at Bianchi. After I shot the mover event I went to the practice range to confirm zero at 50m. Put them all in the X ring! I had tested it before the match, but I wanted to recheck it.
The grips I made from Honduran Rosewood (shut it Wayne). The Prone pad is from Warren, raises the gun up for prone shooting. The trigger is an X-line trigger, I have another post on that elsewhere on this forum. The rules specify a minimum 2 pound trigger pull. I set up the X-line as a two stage trigger, 1 pound initial and 1.03 additional pounds for the second stage. Very, very easy to shoot groups with this set up. This trigger makes the 50 meter line a snap. Sent it to Black Dove for the insane Cerakote job. I specified the colors (something go with the grips) and he knocked it out!
