"This gun is a great gbb. You can't beat AMS's price either! It shoots at 290-300 FPS (Very Good For a Compact Pistol). The mag is a 3.8 Hi capa size. Standard 5.1 Hi capa mags fit too, they just extend a little bit out of the mag well. The kick is nice and crisp. Also, the gas efficiency is amazing! I was able to get 3 mags out of one fill of gas! I love the slightly open style frame WE added to this gun. You might be hesitant to buy this because it is a WE, but DO BUY THIS PISTOL! YOU WON'T REGRET IT! The fiber optic sights are nice too. Hop up can be easily adjusted by popping out the slide catch and sliding of the slide to reveal the hop up underneath. I rate it 10/10 would buy again as a gift perhaps. My YouTube unboxing/review/shooting test will be coming out shortly. My channel name is Jeremy Woo. Check out the video and definetly don't hesitate to buy this awesome gbb pistol."
