High Pressure Air. It is usually from an external rig. Pretty much a compressed air tank.

To add on to this it is a bottle of some sorts that usually is made of metal of fiberglass, which can be placed under pressure. So in a way it is a mini version of a air compressor, but with a set amount of air in it.

As my pistol instructor says "If you have to reload you better be shooting at an army" Which means if you need more then one shot then you need to practice.
Joking aside I would get the long mag and tap that, its 29 rounds of HPA death. Also do not go and drill and tap all of your mags keep at least one you can run propane on, because you never know. Also buying and tapping 7 mags would cost you close to $300 and thats the sucky kjw mags. One tanaka short mag is 60 shipped ( the cheapest I found).

Your best bet, keep a speed loader, count your shots and reload when no one is around, and when you do reload have your pistol very very close buy. I cant count the times I have gotten shot when reloading.

Also with the above method of on/off you have a very loud popping noise when you disconnect the coiled hose, to put it on the next mag.

Most likely you wont need to fill it in the filed, you talking thousands of shots before you run out of air. Also I have seen rigs that use co2 that fit in the stock of the gun, or HPA rigs that fit in a small utility pouch. But all of the pros completely out way the cons, for this mod.

Any gas rifle. HPA is an alternative to propane (which is green gas).

Green gas is the alternative to propane, the more expensive alternative. Then the HPA mod was made to combat the bad effect of gas guns in cold weather, dont qoute me on this some guy made it in his back yard then wanko killed him and took it and made it his love baby.

Anyone tried an HPA pistol?

Umm I would ask wanko about that one. He is the god of HPA guns .
