Things I liked: Rugged, sturdy plastic construction. Feels solid and has a good weight to it. Seems to be accurate, works exactly the way it should. The slide locks back when empty, like a real firearm, and it's pretty cool. The resevoir in the magazine holds plenty of BBs/pellets, and the rail on the bottom is perfect for mounting a laser.
Things I would have changed: Even with the resevoir in the magazine, it would be nice if it shipped with an extra magazine as well. The slide lock/release system would make for a really cool reloading sequence. That aside, the instructions is comes with could be clearer (some people think the slide lock means their gun is broken, for example) and it probably isn't the BEST gun you could have in a fight.
What others should know: I immediately equipped mine with a laser and have only short targets with it; however, it is a very solid, study gun with a good punch to it. The slide is SUPPOSED to lock back whem empty. The first few times, the slide may lock back every time; this can be remedeied by pointing the gun UPWARDS when you cock it. Other than that, a very satisfying pistol, especially for the price.
