Things I liked: nothing
Things I would have changed: Like others, mine shoots 4-6 inches to the left at 15 feet. Gun is noisy. The BBs rattle around in the mag. Sounds like a toy.
What others should know: Buy the HK P30! It has almost the same body, a metal slide, accessory rail, and just looks much better in person. ...and also shoots straight!
Things I liked: Very sturdy and realistic for this price! The metal slide and the details make it look and feel real. The hand grip is very ergonomic.
Things I would have changed: The only thing shy of perfection on this gun is that the hammer is not functional, but you get over it quickly.
What others should know: If you are at all interested in this gun, buy it. It is a great value for the price.
