Amazing, amazing, amazing gun. This thing feels like the real steel. The mechanisms are fluid and the blow back is not the strongest I've ever felt on a gbb gun but does give you enough kick to make you jerk a little. It's loud, sexy, and weighty. Just like it should be. The full metal construction is superb.
Magazine slides out easily since it's full metal too, so sexy
Gun also accepts CO2 magazine (so long as it's made for an M9)
Rail System for lasers or tac lights
Price (but you pay for quality)
Gun cocks back a little too easily, sometimes poses a problem when holstering your gun. I solved this by holding the cocking pin forward when putting my gun back in my holster. Maybe it's just my gun but just a heads up. This minor thing doesn't make me regret the purchase one bit.
