My first GBB Pistol and I am loving it.
The WE Magazine that came with this doesn't leak, but the little plastic slide on the side broke so that prevents the magazine to stop the slide back when its out of BBs and I can't pull the little slide down to easily load BBs anymore.
I also bought a silver WE 15 rd single stack magazine at the same time i purchased the gun and that magazine leaks, had the plastic peice also break, and the bottom of the magazine has a gap and its wobbly.
overall the gun is great but both types of magazine are HORRIBLE
the magazines are just horrible
I had a little issue where my slide would get stuck and I would have to smack the back of it so the slide would move(it wasn't because of the slide catcher). It stopped doing that so its fine now
