Here is my workhorse PGP2 or PGP 2k1 as some call it. It isn't the prettiest thing ever, but it does a great job at getting the job done. Has some scuffs and blemishes around the bottom of the frame, where the front sight is and where the pump handle is. What I was looking for in a pump pistol was something with a longer barrel than the original PGP, with the mods already done to it. I did a home brew to the sights but as you might be able to see in the picture below they line up pretty good and are sighted in at 60 feet.
Cartridge Valve (pretty sure all the PGP2's had them)
Quick Change Threads
Black Trigger Shoe
PMI Rubber "Battle Grips"
Polished Bolt and Hammer
Speedfeed with Rear Sight
Metal Front Sight & Plug
Homebrew Widgets (work well, don't look so good)
