Black Mamba™ Premier Chambers Custom Open Pistol

black-mamba-2Chambers Custom is proud

to announce the first ever Open Gun.

This gun features a Kart barrel chambered in 9mm. The gun is set up to shoot 9mm Major for USPSA Open Class but can be used for plinking if you so desire.

The frame is an STI with polymer grip that features my aggressive stippling pattern. The slide is a Caspian. The comp is custom made with an incredible new design that makes it super flat shooting.

All trigger parts are the new CCP offerings as is the slide stop, grip safety and scope mount. The trigger itself is a long flat trigger by Everglades Ammo that can be cut to the length you desire before it ships.

The gun has a steel mainspring housing to enhance balance as well as the Dawson Bighands Ice magwell with polymer insert for fast reloading.

It comes complete with a Leupold Delta Point red dot optic, one MBX 170mm mag and hard case.

The finish is my standard of blasted “rounds” and polished flat and small parts. The entire gun was blued personally by Joe here at Chambers Custom™.

It is brand new in the safe and available for immediate delivery.
