The Colt 1911 Competition Series 70 in .45 ACP is purpose-built for shooters who demand a reliable, accurate platform for defensive carry or competitive shooting. 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. At 36 ounces, it strikes a balance between heft for recoil control and practical carry weight for a full-size .45 ACP.
This Competition Series model ships with a Novak fiber optic front sight paired with an adjustable rear sight—a combination favored by competition shooters for both speed and precision. The manual safety and grip safety give you the security and control that serious .45 shooters expect. The 8+1 round capacity is standard for the 1911 platform, offering adequate firepower without sacrificing the gun's compact profile relative to modern service pistols.
Whether you're prepping for a local 3-gun event, running drills at the range, or seeking a dependable .45 ACP for home defense, the Competition Series 70 delivers the accuracy and consistency that earned the 1911 its reputation.

The Competition Series 70 is engineered for accuracy and control, making it a solid choice for defensive training and competition. The match-grade barrel and sight system prioritize precision, and the .45 ACP chambering is proven for stopping power. 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.
