Another custom handgun built with PGC and PDI parts at RedWolf Airsoft and hits hard at 310fps... "The pistol is able to shoot all BBs and lock back with the supplied original recoil spring. With the enhanced recoil spring, the pistol was able to shoot all BBs but did not lock back. Both are included in the box, so you may choose which one you prefer to use. 

The PGC kit includes quite a bit of parts and most of the Tokyo Marui parts are completely usable. (The only thing we could fault with the Tokyo Marui was that the frame, slide and outer barrel were plastic and lacked proper markings...) In addition we decided to use the PDI Winter type piston head, which has altered dimensions to provide a longer blowback stroke."
