Description
The Colt 1911 Government Series 70 .45 ACP 5″ Blued is the full-size, single-action 1911 that built the legend—and it’s still built right here in the U.S.A. Chambered in .45 ACP with a 5-inch barrel, this blued carbon steel pistol wears double-diamond rosewood grips and fixed high-profile sights. It uses Colt’s Series 70 firing system, meaning no firing pin block, just a crisp trigger and classic lines. Whether you’re punching paper at the range or adding to a collection, this is the real deal.

Key Features
- Series 70 Firing System – Why it matters: No firing pin block means a lighter, crisper trigger pull that shooters and competition guys prefer for accuracy.
- 5-Inch Carbon Steel Barrel – Why it matters: The full-length barrel gives you maximum velocity in .45 ACP and the sight radius you need for tight groups at the range.
- Double-Diamond Rosewood Grips – Why it matters: Classic look that feels right in the hand, with enough texture to keep the gun planted under recoil.
- Fixed High-Profile Sights – Why it matters: Easy to pick up quickly, and the white dots help in low light without adding bulk.
- Blued Carbon Steel Frame & Slide – Why it matters: Traditional rust-resistant finish that wears in beautifully and holds up to regular use.
Who It’s For
This Colt is for the shooter who wants the original 1911 experience—no frills, no gimmicks, just a rock-solid .45 that’s been proven since 1911. It’s a top pick for target shooters who appreciate a single-action trigger, collectors who want a faithful reproduction of the Series 70, and anyone looking for a reliable full-size handgun for range days or home defense. If you’re new to 1911s, this is the one to start with.
Pros & Cons
- Pro: Legendary reliability and accuracy right out of the box. The Series 70 trigger is one of the best factory triggers on a 1911.
- Pro: Classic blued finish and rosewood grips look sharp and hold up well with basic care.
- Con: The fixed sights are fine for most shooters, but if you plan to run optics or night sights, you’ll need to have a gunsmith swap them out.
- Con: The blued finish requires regular oiling to prevent rust in humid environments—it’s not a stainless gun.

FAQ
Is the Colt 1911 Government Series 70 .45 ACP 5″ Blued a good choice for a first 1911?
Absolutely. It’s the standard all other 1911s are judged by. The single-action trigger is easy to learn, the .45 ACP recoil is manageable with the steel frame, and the reliability is proven. Just keep in mind it’s a full-size gun—not ideal for concealed carry unless you’re built like a linebacker.
Does this model have a firing pin block?
No, it uses Colt’s Series 70 design, which means no firing pin block. That gives you a cleaner trigger pull with less creep. Some shooters prefer this for accuracy work.
Will this Colt accept standard 1911 magazines?
Yes, any quality 1911 .45 ACP magazine will work. Colt ships it with one 7-round magazine, but you can use 8-round or 10-round aftermarket mags without issues.
Is the finish durable for regular range use?
The blued finish is traditional and looks great, but it will show holster wear and needs occasional oiling. If you plan to shoot it heavily, consider a stainless model instead. For casual range trips and display, it’s perfect.
