The Colt Government Delta is your grand daddy’s pistol in a power-packed caliber. This time-tested design is available in the 10mm cartridge. Colt says it “was one of the original pioneers in adapting a combat pistol to the potent 10mm cartridge and the first to successfully manufacture a 10mm caliber pistol in the United States.” This gun is great for combat shooters, 1911 fans and hunters who want the power to hunt medium-sized game in a 1911 style pistol.
