Personally I dont like pump pistols (ie PGP). Pumping a gun that is in your armpit is one thing cause you can pull the pump against your body keeping the gun in firing position the whole time. Whereas a pistol, you usually have to drop the barrel each time you pump and pull your arms in to pump it. Even stock class guns you rock them down slightly then back up. Pump pistols just are too much time off target IMHO.
