Things I liked: The Defender has some heft to it similar to the real thing. It was bought to help with trigger control. I have no problem hitting 16oz plastic bottles from 20 yards away. A Springfield holster for a 1911 with a rail works ok for practicing draw techniques.
Things I would have changed: Move the safety to where it is supposed to be.
What others should know: Loads of fun. Quiet.
Things I liked: The engineering in this gun is great. The detachable magazine is theoretically fantastic.
Things I would have changed: The quick-out-the-door manufacturing put to shame any "great" engineering. It took probably 20 minutes before I was finally able to shoot this gun: 1, A bb fell out of the magazine and got jammed in the magazine well. 2, The gas cartridge screw was extremely difficult to seat. 3, Constant misfires I remedied 1 and 3 by disassemling the magazine, streching the bb retaining spring slightly, deburring the bb retainer with a file, and reassembling the magazine. While I was at it, I filed the 2 notches meant to hold the magazine open while loading. Number 2 I used a pair of pliers to tighten the gas cartridge screw. After these fixes I could get through a whole magazine with only one of two misfires which I attribute to the bb quality.
What others should know: This gun is fun, I hit 10 inch stainless steel dog dishes from 20 yards no problem. The gun looks as though it will fit a 1911 with a rail holster. On the other hand, I am glad the Colt defender came in before this one. It was money well spent.
