speed changer, gated feedneck, but nothing is really NEEDED.
Built like a tank
Most accurate marker I've ever used
stock class 100%
...It's not made anymore...
Ok let me start off by saying I use this little monster as a primary and NOT a back up.
That being said, after using the pgp for a year I have noticed my game improving dramatically, I've had to lear to pick my shots, snap shoot, MOVE, communicate with my team all in about 2 games of playing with this thing. The fact is, you MUST learn these skills to play with the PGP and learning them makes you a better player.
Now on to the build of the marker. The over-all construction and durability is incredible, I have thrown mine against a tree just to prove that point! A few design flaws include the 14-turn CO2 nut and the plug for the feed tube. But with a few dollars or alot of elbow grease both of these "problems" can be easily solved.
The PGP is extremely accurate, but a little picky on paint, the cheap stuff with burst in the small barrel and the high end paint will roll. This can however be fixed with the help of an airsmith if you find it to be a constant problem.
Air efficiency is great, I get about 25-28 good shots off of one twelve gram with the stock hammer (An airsmith can lighten the hammer for you which would increase gas efficiency even more!)
All in all, I love mine, and I don't ever want to part with it. The Sheridan PGP is a piece of paintball history and an incredible marker (You should see the looks on people's faces when I tell them it's older than I am haha)
