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.

This is a table top review of the Umarex Colt Defender CO2 BB pistol. I show you around the gun and walk you through its basic operation and handling. I have included a target example showing you a grouping I got from 20 feet out with this gun. The Colt Defender is mostly metal so it has a very solid and durable feel.

The Umarex Colt Defender is well made and is a fairly good replica of the real 45 auto Colt Defender firearm, and at a very affordable price. It's also a decent shooter with a fairly high 440 fps and has decent accuracy for a smooth bore BB gun.
