Description
There is something about a stainless Government Model that never gets old, and Colt built this one to do more than look good in the safe. The 1911 Competition Series 70 takes the classic full-size frame and dresses it up with the parts that matter when a timer is running: a 5-inch National Match barrel, a Novak adjustable rear sight paired with a red fiber optic front, and the Series 70 firing system that gives you a clean, crisp break without the extra parts of a firing pin block. If you have ever wondered why match-focused 1911 builders keep going back to the Series 70 design, one trigger press here will explain it.
Built to Run Fast and Stay Flat
Colt gave this Competition model a dual recoil spring system, which does two useful things at once. It softens the push of full-power .45 ACP so the sights settle back on target quicker, and it stretches spring life so you spend more time on the range and less time swapping parts. The undercut trigger guard and upswept beavertail grip safety let your hand ride high on the frame, and the checkered blue G10 grips with their scalloped pattern lock in without chewing up your palms. At 36 ounces of all-steel heft, this pistol soaks up recoil the way only a Government Model can.
Series 70 Details Worth Noticing
The brushed stainless finish shrugs off sweat and holster wear better than blued steel, and the blue G10 grips against that silver slide make this one of the sharper looking pistols in the case. The Novak rear sight adjusts for windage and elevation, so you can dial in your preferred load instead of chasing a fixed sight. Colt even tosses spare sight fibers in the box, a small touch that regular range shooters will appreciate down the road.
Who the Colt Competition .45 Makes Sense For
This is a strong pick for anyone getting into action pistol matches, bullseye practice, or just wanting a proper American-made 1911 that earns its keep at the range. It feeds from an 8-round magazine for 8+1 total, and it carries the pony on the slide, which still means something.

Frequently Asked Questions
What is the difference between the Series 70 and Series 80 firing systems?
The Series 70 design skips the firing pin block found in Series 80 pistols, which means fewer parts in the trigger path. The practical result is a cleaner, crisper trigger pull, which is exactly why Colt chose it for the Competition line. Many 1911 fans prefer Series 70 guns for range and match work for that reason.
Are the sights on the Colt 1911 Competition adjustable?
Yes. The rear is a Novak adjustable sight, so you can fine-tune your point of impact for different bullet weights and loads. Up front you get a red fiber optic that picks up light and draws the eye fast. Colt also includes spare fiber rods in the box in case the front fiber ever needs replacing.
How does the dual recoil spring system help?
The dual spring setup spreads out the recoil impulse, so the pistol feels softer shooting than a traditional single-spring 1911 in .45 ACP. It also extends the service life of the recoil spring, meaning longer intervals between spring changes for high-volume range use. Combined with the 36-ounce steel frame, this is a very manageable .45.
Will the Colt Competition Series 70 accept standard 1911 magazines and holsters?
It is a full-size Government Model, so standard single-stack .45 ACP 1911 magazines will run in it, and it fits holsters cut for a 5-inch 1911. It ships with one 8-round magazine, and quality spares from Colt, Wilson Combat, or Chip McCormick are easy to find. Just note the adjustable rear sight when picking a tight-fitting holster.
