Built on the proven Series 70 design, this full-size pistol combines classic 1911 ergonomics with modern competition-ready features. The 5-inch stainless steel match-grade barrel and stainless steel slide deliver the accuracy and durability expected from a Colt, while the gray G10 grips provide a secure purchase in any weather.

Whether you're preparing for competition or serious defensive work, this platform has earned its place in both arenas.
The Colt 1911 Competition Series 70 is chambered in .45 ACP, the standard cartridge for 1911 platforms. It will function with standard commercial .45 ACP ammunition, including both full-metal-jacket target loads and hollow-point defensive rounds.
The Novak sight system is widely recognized and compatible with many aftermarket upgrades. We recommend consulting with a qualified gunsmith or the manufacturer if you're considering sight modifications to ensure proper installation and function.
Match-grade barrels are manufactured to tighter tolerances and higher precision standards than standard barrels, which contributes to improved accuracy and consistency—especially important in competition settings where tight groups matter. The stainless steel construction also offers superior corrosion resistance over the life of the weapon.
