Just bought one for fun. I am impressed. After owning a S&W model 19 made by Marushin in the early 1990s I decided to take the plunge and get a Derringer as a humiliation weapon for CQB. The finish is suprisingly high quality, and the gun weighs plenty for it's size. The range is about 20 metres max. Though is suprisingly accurate indoors. I would say it does about 180 fps on 134a using a .20 bb. Very fun. Comes well lubed and a little stiff. Expecting it to wear in. Time will tell how it holds up, but I feel confident it will last a good year or two. Worth the money just to say you own one of these. Do not buy it expecting accuracy and skirmishability, you will be disappointed. Just get one as a laugh and you will have a smile on your chops. 5/5 for what it is! Alex R.
