Things I liked: Accuracy is very good. Weight is comparable to fully loaded compact semi-auto. Blow back action gives the feel of real semi-auto. Great for learning point-and-shoot without excessive recoil, noise, and expense of ammo. And no need to clean!!!
Things I would have changed: Plastic threading on muzzle would be better made of metal. Also rail assembly makes the gun front heavy even without accessories. Cannot use iron sights with silencer attached. Silencer is more cosmetic than anything else, it does little to surpress noise.
What others should know: I just got this gun today and ran about 50 rounds through it. It is very fun to shoot. It's a great addition for those plinkers that want an accurate pistol that is really cheap to shoot.
