The Colt Defender is an excellent replica of the classic Colt Defender. The Defender is a compact version of the Colt 1911 pistol. This replica pistol is constructed out of metal (except the grip panels) and gives the Defender some authentic feeling heft to it.

The trigger on this unique pistol is double-action-only with a smooth pull and a fairly crisp release.  The hand grips have textured grip panels and is comfortable to hold and has a lovely feel.

The Defender features a blade and ramp style front sight and a fixed rear  sight.  A white dot on the front sight has been added to help line up the sights easier. AndThe safety is located on the right side of the gun, just above the trigger. The safety  requires you to push in first then slide it on/off.


The button near the trigger on the left side of the gun that would typically be the magazine release on other BB guns, is actually a button to activate the spring powered sliding grip panel. The Defender is powered by a single standard 12g CO2 cartridge inserted into the hand grip behind the slide out grip panel. Under the barrel of the Defender is a Picatinny style rail for mounting accessories such as a laser sight, flashlight and so on…


The magazine Of the defender is built right into the gun.  You can load a total 16 BB into the built in clip. Loading the BBs is pretty straight  forward. Just Pull the follower down and lock it. Load the BBs through the loading  port, and then unlock the follower.
