Sibling Colts. A 10mm Delta Elite and a Colt .40 S&W. Both made in blue by Colt. These are part of the twelve gun "Caliber Project". Each of Colts factory made calibers. The build are all similar in features with new barrel, checkering, beavertail grip safeties, Chen Max Bevel MSH. BoMar style rear sights, flat tops and serrations with ball cuts. The finish is classic blue with nitre blue accents and Spegel grips from the same block of French walnut. Eight down, four to go. Maybe another by Christmas- if I can say that. Enjoy.
