Hey,
I'm a big Airsofter and I would recommend the sig sauer P226 pistol I own 3 of them and they are a great gun. I amd getting a new one that is a gas blow back and it will make you bleed at medium range. When you airsoft wear goggle because they will blind you if you are hit in the eye. I like to wear a full airsoft mask because getting hit in the face isn't very fun.
Good Luck,

Take-Em
