With the upcoming Biohazard/Resident Evil: Revelations 2, it might be time for you to look into the Samurai Edge Gas Blowback Pistols. In stock at AirSplat.com is the HK3P Samurai Edge Barry Burton MOD GBB Pistol, which can be fired in full auto too. If you're looking for something more affordable than the Tokyo Marui version (which is the official airsoft version), then this HK3P version can be an alternative.
