I shot the original pgp pump, and it was pretty good. This one is a little more accurate, and alot easier to pump. I can shoot any brand paintballs(from walmart anyway) and it will score a direct hit. Its good for close range, and medium range. Dont even try long rage, its a waste of time. Its very efficent on co2, maybe 15 shots on a 12 gram cartridge. And all of you guys saying that thing u pull back to put the paintballs in breaks. Hasnt broke on me yet, i shoot it everyday. I pull back that thing for the fun of it. View loader paintballs, have seemed to work best on this gun. Sheridan prenium paintballs are better tho. But brass eagle paintballs also *uck this thing up. Brass eagle paintballs are so deformed, that they get stuck in the barrel, and its hard to get out. It has a good velocity adjustment, which comes in handy.
Weaknesses:
Dont put brass eagle paintballs, or dog food in this gun.It just *ucks it up really bad. A little heavy
Conclusion:
This is a handy side arm, incase something goes wrong with ur main gun. Its easy to pump, and accurate. A little on the heavy side tho. Maybe thats just me.
