Mag Tactics does a video review of the VFC M17 Gas Blowback pistol. This actually made by VFC for the SIG Air ProForce, the airsoft division of SIG Sauer and thus, it is an official airsoft gun based on the M17/P320 pistol. He also points the problems he encounted when he further tests the GBB pistol... "I was making a shooting video with this gun, but the hammer spring was broken. As a result, I turned this into a review instead."
