My cannon broke and pipe is stuck inside fitting!

Cannons powered by pneumatic pressure (compressed gas) using a valve or other release.

replace all the fittings. They can't be that expensive, and you are just asking for trouble using DWV otherwise.
I'm weird, I know it, you don't need to tell me.

No its not, I just had some 260psi rated PVC explode next to me and two friends, no one was hurt but that was just pure luck it missed us all.
I've passed the solvent welding course so I know what im doing there and the gun has never been banged or dropped to weaken the fittings so I take it was just a fault in the fitting, though they aren't meant for air pressure.

I've passed the course, too. I thought DWV fittings were okay to use.

Some site that I can't find on Google. He said even though the fitting said DWV it should hold pressure because the PVC pipe said DWV. (All the PVC pipe I get says DWV but it is pressure rated).

No, your pipe can have DWV on it, but it still must have a pressure rating too.
Fittings though must have nsf-pw on it, and have deep sockets.
