Things I liked: For a BB gun, this pistol is scary-powerful. If you like to see targets shatter, or metal pierced by a lowly BB, this is for you; videos guys have put online attest to this. It is also quite accurate. Part of this pistol's appeal may be that is is somewhat crude in many design elements, but when it comes to shooting, it is pretty accurate and authoritative. It is not a work of mechanical art, but it does its job.
Things I would have changed: I think the union of the gun and the magazine needs to be smarter. Often the first shot after loading can be an "ify" proposition; many people note some jamming issues. I don't consider this a deal breaker, but firing this gun after loading is not a matter of popping in the magazine and letting it rip. Loading the magazine is a delicate operation, as the topmost BB in the mag is likely to rattle out of place. The cartridge holder is also somewhat primitive, even compared to a Taurus Airsoft CO2 I also have. Once it gets going, though, its operation is fool-proof and brisk.
