Colt Government 1911 A1 Pellet Pistol CO2

Type: Pellet air pistol
Manufacturer: Umarex
Model: Colt Government 1911 A1
Materials: Mostly metal construction
Weight: 2.5 pounds
Barrel: 5 inches, metal rifled
Propulsion: CO2 x 1
Action: Semi auto, single and double action
Ammunition Type: .177 caliber pellets
Ammunition Capacity: 8 rotary magazine
FPS: 425

Trigger Pull: The trigger pull on the Umarex Colt Government 1911 A1 is extremely nice in both single and double action mode with the single action having the lightest pull making it a joy to shoot at targets.

Accuracy: I shot this air gun at a target from 20 feet away in a free standing position, and it performed excellent getting just over a one inch grouping close to the center of the target, just a little bit high. The sights can be adjusted for windage if you are shooting a tad bit to the left or right. My Chrony testing with an eight shot averaged result was 383 fps.

Build Quality: This is an almost all metal air gun with great fit and finish and a nice hefty 2.5 pound weight to it. It's made in Germany, what more do I need to say? The only plastic parts to speak of are the grips which almost feel like a mix between rubber and plastic. All the mechanical parts operation are as smooth as butter.

Realism: The Umarex Colt Government 1911 A1 is a licensed replica of the real Government Colt 1911 A1 45 auto pistol. It looks pretty much bang on with the exception of the slight break in the slide where the rotary magazine is accessible.


  • Almost all metal construction - good weight and very solid feeling gun - 2.5 pounds!
  • German made.
  • Comes in a nice hard-shell case.
  • Adjustable rear sight for windage.
  • Double and Single Action, very smooth and light.
  • Accurate trigger design and working back-strap safety
  • Very good accuracy, decent FPS for a pellet shooter and good usage of CO2


  • A bit on the pricy side $200+.
  • The sights are a bit hard to see on certain darker backgrounds.
  • The engravings on my airgun where a bit hard to see.

Comments: The Umarex Colt Government 1911 A1 is a pleasure to own and shoot, you can really tell this is a quality gun from how smoothly it operates and the confidence it gives you even just holding it in your hands. This well-made airgun has been around since the late 90's and even today holds its own. It may not have a working blowback design or drop out magazine but as far as being a top notch airgun made for shooting and enjoying for years to come, it definitely succeeds in that category.

A must-have gun for any serious collection

Surprisingly no reviews so far on this beautiful piece of hardware... I purchased 1911 about a year ago and have been very satisfied with it essentially in every aspect. Build quality is close to perfect (one thing left to desire design wise is the magazine changing procedure which often ends up with a magazine fall out on the ground, - presumably a rather common design overlook for many other models too...). The trigger pull is unbelievably soft and responsive which positively contributes to accuracy of shooting. Velocity is also pretty decent, especially when quality pallets are used. The instance I got did not require any calibration sights-wise and/or substantial behavioral adjustment to compensate for natural misalignment due to elements, breathing, weight, etc. If you consider owning an item from this category (a pellet airgun that is), you owe it to yourself to get this one. Chances of being disappointed with such a choice are close to zero.

This is a table top review of the Umarex Colt Government 1911 A1 CO2 .177 caliber pellet pistol in the Nickel finished version. I show you around the gun and walk you through its basic operation and handling. I have included some video of a target example showing you an 8 round grouping I got from 20 feet out with this fine pistol. I also put the pellet shooter on the Chony Chronograph to find out its real world feet per second rating. The Umarex Colt Government is almost all metal and is extremely well made.

The Umarex Colt Government 1911 A1 is very well made and finished and makes an excellent replica of the real Government 1911 45 auto Colt firearm. It has great feel in both single and double action making it very easy to shoot on target.
