this is the nicest full metal air soft revolver i have seen it is a much more correct copy of a Dan Wesson with the right frame size and the cylinder lock on the crane where it should be,,grips are a nice feeling and rubberish like the houge ones they are copied after..they are solid on the gun and NO wiggle at all..there is a folding hex key on the removable side to tighten the screw. gun also has an adjustable hop and a Allen key is supplied to adjust it.
