TSD Sports UG138SR 4 Inch Gas Powered Non-Blowback Airsoft Revolver (Silver)
This is a very cool revolver just like the westerns. It has metal components for added weight and more realistic feel. Functioning hammer and rotating cylinder so it feels like you're right there in the action. Gas powered so it has a little more kick than its little brother the spring revolver (which is also a good buy).
