    Things I liked: Love the realistic sound, realistic action, this is my first gas airsoft gun, and not my last. Shot 2 full mags of bbs tonight in 35 degree weather, gun performed flawless. Just make sure u have good green gas! Found out the hardway!

    Things I would have changed: Nothing I can see!

    Things I liked: Bought this one more out of curiosity than anything else, since it's a 'dual fuel' - goes w/greengas or CO2. I was pleasantly surprised by the look, feel and power of this critter right out of the box. Changing over from the GG mag to the CO2 is simply a matter of popping out one mag and inserting the other, which is simple and convenient.

    Things I would have changed: The front portion of the slide, with the front sight attached is held on by a very small set screw. This worked loose on mine and the slide/sight assembly fell off. We were lucky in finding the tiny screw, since we were shooting outdoors. Once re-tightened it's staying where it belongs, but buyers should check and tighten this one before you shoot it. The CO2 mag is too expensive IMO, but probably worth it just to get away from the GG.

    What others should know: This gun shoots hard, even with GG and harder with CO2. It's accurate at short distances and a lot of fun to shoot - which is what it's all about anyway. Well worth the price.

    Things I liked: The realistic feeling. The guns weight, shooting sound, recoil, magazine, and even locks back when your out of ammo like a real pistol! It will dominate. My friends are afraid of me now whenever i pull it out, and i got them into gas guns..theyre the best, it beats cheap plastic pistols. this is good reliability, quality, strength, and versatility. thats all one needs for a good time.

    Things I would have changed: This gun pretty much has it all.. i love the style WE makes their guns. so just keep up with the tasty designs, because all everybody wants is sweet looking gun with power. This gun has it along with some other made by WE

    What others should know: DON'T TRY AND ACT GANGSTA WITH IT AND SHOOTING IT SIDEWAYS!!! i've heard doing that makes all the insides messed up. My magazine releases green gas, i think something in it got damaged from little accidents so i suggest getting 2 magazines. u should have 2 anyways, because they get really cold and start to shoot poorly if you only use 1
