Things I liked:Mostly metal construction. The slide locks when the magazine is empty. The blowback give a good "feel"to the gun.
It definitely does not feel like a toy! Things I would have changed:Despite the mostly metal construction of the gun, the magazine is plastic. It makes you feel like they cheaped-out on things.
Spare magazines are extremely hard to find
Sights are non-adjustable.
What others should know:The one real knock against the gun is the magazine.
All things considered, even with its few flaws, it is one of the lowest priced blowback guns and an excellent value for the money.
