Colt's Series 70 .45 Fires 1,000 Rounds With Three Stoppages
A Colt Series 70 Government Model in .45 ACP fired 1,000 rounds of FMJ and hollowpoint ammunition with three stoppages, and it did so as a used gun with no babying. The reviewer ran the pistol through the same 1,000-round test he applies to every handgun, and the plain GI-style 1911 held up better than he expected. The pistol earned a permanent spot on his range bag, and the trigger improved as it aged.
Key Details
The test gun is a Colt Series 70 Government Model Classic with a matte blue finish, GI lines, and checkered rosewood grips. It carries a 5-inch stainless National Match barrel and a GI guide rod and barrel bushing. Colt chose a checkered polymer mainspring housing that matches the matte forged steel frame.

Background
John Browning's design became the U.S. Army's sidearm in 1911, and the Model of 1911 carried the Army through two world wars. Colt produced the original pistol and later the M1911A1, which added the arched mainspring housing and the short trigger. The Series 70 designation covers Colt's production run that kept the original design largely intact, with no firing pin block. Colt introduced the Series 80 in 1983 with an internal firing pin safety and a plunger that many shooters dislike. Colt still builds Series 70 guns for buyers who want the older lockwork. The Government Model you see today borrows features from the 1911 and the A1 while keeping modern tolerances and MIM parts. That mix makes the gun more of a restored classic than a museum piece. Colt's catalog now spans 3-inch Defenders, competition 5-inch guns, and optic-ready models, but the Series 70 remains the purest link to the original.
Why It Matters for Gun Owners
Buyers who want a no-frills 1911 now have a real option in the Series 70 Government Model. The gun skips the firing pin safety, which makes the trigger easier to tune and easier to predict. Owners who plan to carry should weigh that trade carefully. Series 70 pistols do not have the internal block, so they depend on the grip safety and the thumb safety for safe handling. Anyone carrying a Series 70 must train with the manual of arms and avoid dropping the hammer on a loaded chamber. Shooters who prefer a Series 80 can still find those guns in Colt's lineup. The .38 Super option matters too. Owners in states that restrict .45 ACP magazine capacity should check local rules before buying the seven-round .45. Many owners also run aftermarket magazines, so verifying compatibility with the MIM feed lips and the magazine release remains essential.
DownRange Analysis
Does a 1911 with a Series 70 lockwork survive Bruen scrutiny? Bruen asks whether a modern firearm regulation fits the nation's historical tradition. The question here is not about the gun's legality. The 1911 design sits squarely in the American tradition of arms carried for self-defense, and no court has pushed back on the platform itself. Market-wise, Colt's willingness to keep a plain Series 70 in production signals demand from buyers who want a traditional gun without the extras. Three stoppages in 1,000 rounds on a used pistol is a respectable result, but it is not a clean bill of health. Anyone who buys one should run a full function check, replace worn springs, and keep the gun clean. Fire a few hundred rounds of your carry load before trusting it. The trigger improvement from 5.5 pounds to under 4 pounds shows what a few hundred rounds can do. Shoot it before you assume it is ready.
