Please use the search button and do some research:
1) Translucent/clear/tinted lower receivers are not and were not necessary for legal importation of an airsoft gun (be it pistol or rifle).
2) Translucent/clear/tinted lower receivers have allowed lower velocity airsoft guns to be imported ONLY due to an INTERPRETATION of the law.
Full Metal pistols tend to be more durable and definately more realistic, but price may sway someone towards a tinted lower pistol.
