Type: BB air pistol
Manufacturer: Umarex
Model: Colt Defender
Materials: Mostly metal construction with a few plastic parts
Weight: 1.6 pounds
Barrel: 4.3 inches, metal non-rifled
Propulsion: CO2 x 1
Action: Semi auto, double action
Ammunition Type: 4.5mm BBs
Ammunition Capacity: 18 round magazine
FPS: 440

Trigger Pull: The trigger pull on this gun is medium and a bit long; the break point is a bit hard to predict but once you get used to it being on the long side it shoots pretty good.

Accuracy: This was my second time shooting the Colt Defender at a target from 20 feet away in a free standing position, and again it performed about the same as the first time with a decent 2 inch grouping. I think with practice, I could get this easily down to a 1.5 inch group.

Build Quality: As the Colt Defender is almost all metal, you can't really complain too much about the durability aspects of this gun. Where I was let down a bit was the lack of functionality. In other words - parts that normally served a purpose like the hammer, slide release, sight adjustments and rear safety - all where just moulded into the metal gun and where only for show.

Realism: The Umarex Colt Defender is a licensed replica of the real 45 auto Colt Defender pistol. It is a close looking copy with the exception of the trigger mechanism.


  • Almost all metal construction!
  • Good accuracy and power combination
  • Very solid and durable air gun
  • Decent replica of the actual Colt Defender 45 auto


  • Most of the mechanical parts are moulded into the gun
  • I don't like the screw holes on the right hand side of the gun - a dead giveaway
  • I would have liked a drop out magazine
  • Ejection port metal material is only a plastic sticker

This is another low-cost replica air gun from Umarex designed for the more entry-level buyer. It's a very solid and well-made gun being that is mostly metal. There are many positive aspects about the Colt Defender: it's fairly consistent and accurate, has all the Colt licensing and trademark, has a good 440fps, uses an all metal design, and comes in at a very affordable price.

The gun you get after a fancy blowback gun

I had a Tanfoglio Witness 1911, which is a very faithful replica, but not a particularly good BB gun. Then I got an Umarex Colt Defender, and it's kind of the opposite, it looks good at a glance, but it's not a very good replica in terms of details. However, it is a genuinely great BB gun. The FPS is MUCH higher than the Tanfoglio and it uses a lot less CO2, I get about 100 rounds per cartridge versus maybe 60 for the Tanfoglio. And the Defender will blast holes through steel cans unlike the Tanfoglio. The extra power makes it more accurate over longer distances, and that makes it more fun to shoot. Both are great guns in their own way, but when it comes to actual shooting, the Umarex Colt Defender has it.

Awesome gun.

Piggybacking on another review as it specifies the pros and cons for myself as well. Pros: Cheap. I like the weight and general fit to hand. I use it to improve point & shoot handgun style shooting. It holds 16 in the clip and this BB pistol holds 16 shots. It works real well for honing eye/hand coordination. Good way to get in the needed practice without burning up a lot of expensive ammunition. The trigger pull is kind of long, but using the point & shoot tech. you use the middle finger on the trigger instead of the index finger so it's not a problem. The sights seem to fine. But with P & S they are not used, and the longest distance at which I practice is 25 feet. I have been getting 96 shoots from one CO2 cartridge. Cons: I really don't like the the logo in the middle of the grip. Would've looked a lot cooler without it. Can't think of anything else.
