G&G Armament will release the GPM9 MK3 Gas Blowback Pistol next month. Check with your retailers if they'll be stocking this once released... "The new GPM9 MK3 has a polymer slide and comes with a 27 round capacity magazine. A Picatinny rail is installed underneath to attach a flashlight or laser.  In addition, a 12mm CCW thread makes it easy to attach our G&G battle owl tracer unit on to it.
