Comments: The Colt Defender, made for Umarex in Taiwan by Wingun, is an all metal replica of the Colt firearm. The controls of the firearm are faithfully reproduced on the Umarex replica but, except for the magazine release, are molded into the frame and therefore nonfunctional. The magazine release, when pressed, causes the spring loaded grips to slide back exposing the BB magazine and the chamber that holds the CO2 cylinder. The trigger on the Umarex is double-action-only (DAO) with a smooth pull and a fairly crisp release. The sights are not adjustable, but they present a good sight picture. The Umarex Colt Defender has excellent power and good accuracy, especially for such a small gun. While the measured muzzle velocity does not reach the figure quoted by Umarex (440 fps), it should be noted that the temperature during the tests was only 67 C. The Defender is very efficient in its use of gas and gets 80-90 good shots per cylinder. This airgun is fun to shoot, inexpensive, and easy to recommend.

Performance: Measurements were made on 1/31/10 at a temperature of 67 F and 14' elevation. A ten shot string was fired from a bench rest at 15' using Daisy Avanit BBs (5.5 gr). The highest velocity measured was 429 fps, the lowest was 422 fps (average of the 10-shot string was 424 fps, s = 2.0). A six shot string fired with open sights grouped at 0.70".

The Colt Defender was tested with RWS BBs, Crosman Copperhead BBs, and Daisy Avanti Precision Ground BBs. The results of these test are shown below.

When fired off-hand at 15' using Daisy Avanti BBs, the Defender consistently produced 5-shot groups between 1.1" and 1.3".


Right Profile: The safety is mounted on the right side of the frame above the trigger and is similar to the safety on many other airguns made by Wingun. The safety is set by pushing it forward and released by pushing it in then pulling back. This is easy for righties, but left-handed shooters will find this difficult.

Front View:

Left Profile 2: The non-adjustable front sight has a painted white dot. The non-adjustable rear sight is painted black. The sights present a clean sight picture for quick target acquisition. The hammer does not move and is molded into the frame.

Right Side Markings:

Left Side Markings:

Loading BBs: The BB magazine is accessed by pushing the mag release button. This causes the spring-loaded grips to slide back. The spring follower locks at the bottom of the loading slot.


Loading CO2: The cylinder tightening screw is hidden by the plastic grip panels and provides a realistic appearance to the airgun. Unlike most airguns with sliding grip panels, the panels of the Defender lock in place when closed. The "mag release" button actually releases the spring-loaded grip panels. The locking grip panels prevent them from sliding around while shooting the Defender. Most other airguns that utilize sliding grip panels suffer from "panel wobble" while shooting.
