Here is a video on one of the most necessary upgrades for a PGP or other Brass Sheridan paintgun, the quick strip slot. The quick strip slot can easily be cut in the body of a Sheridan / PMI PGP which with a dremel and a file. This cut will allow for easy bolt removal.
I typically remove the valve and internals before cutting the slot since the brass shavings can get into the soft plastic of the cup seal and cause leaks. After cutting the Quick strip Slot I also blow he shavings out of the body with a compressor hose.
Also make sure to use proper safety precautions such as safety glasses to avoid metal shards getting in your eyes and gloves so you don’t cut your hand.
For a video breakdown of the PGP (which also applies to other 12 gram based non cartridge valve sheridans) watch this video:
