I like P7's a lot, the one I shot was very accurate.
Aren't they gas pistols?

Hey, Henry! MSWong is a Arms Dealer in the UK and he DO NOT sell gas pistols......

Gas, not as green gas, but gas from the bullet facilitates the recoil of the slide and cycles a new shot.

The P7 is a semi-automatic, blowback operated firearm. It features a gas-delayed blowback system modeled on the Swiss W+F 47 pistol prototype...

Recoil system could not be stated as "gas pistols" as this is not the right wording.

ugh.. alright, fine, so it's not entirely a traditional direct gas/ short/long stroke piston design. However the pistol is still facilitates a gas regulated system and not a blowback recoil system:

It features a gas-delayed blowback system modeled on the Swiss W+F 47 pistol prototype, which uses gas pressure of the ignited cartridge that is fed through a small vent in the barrel (just in front of the chamber) to retard the rearward motion of the slide by means of a piston contained inside a cylinder located beneath the barrel.

so there you go.

and here's a diagram to better state my point.
