I was a bit surprised by the Umarex DX-17 Spring Powered BB Pistol, it actually shot a lot better than I was expecting it to perform. I did have to aim rather low since the Umarex DX-17 BB Pistol likes to shoot on the high side but if you are shooting at closer in ranges then you won't have to adjust your aim point so high.
Getting into my performance testing for the Umarex DX-17 Spring Powered BB Pistol, I placed 5 shots through my Chrony Chronograph and averaged 210 fps which again was very close to the Umarex claimed 200 fps, even a little bit higher! he DX-17 is a single shot repeater but because of the BB reservoir you can quickly reload follow up shots by simply point the Umarex DX-17 Spring Powered BB Pistol a little upward while pulling the slide back and pushing it forward to active the spring piston and load a BB at the same time.
As I mentioned the Umarex DX-17 Spring Powered BB Pistol shot on the high side, at 30 feet it's a good 8-9 inches high but I have a feeling that this is about as high as the BB's will rise since they are not going that fast and gravity will start bringing them back down. At about 10-15 feet out from a target the Umarex DX-17 Spring Powered BB Pistol seemed to shoot about 3-4 inches high so not nearly as bad and this can be adjusted pretty easy by simply aiming a bit under the target you are shooting at. In terms of a 10 shot grouping theUmarex DX-17 Spring Powered BB Pistol got about a 4 inch grouping which I have to say kind of surprised me as I was expecting a much larger spread.
So for about $20 you kind of get what you pay for but I really think with the Umarex DX-17 Spring Powered BB Pistol you perhaps get a little more! It has a really good trigger, seemed to be built pretty tuff, shot exactly right on the claimed fps mark and was even able to keep a reasonable grouping. And to keep costs down even more you never need to buy CO2 so that's another bonus.
