Most 18c's work fine on propane, stock. People have shot thousands of rounds before getting a cracked slide or damaged screw post. At that time you simply upgrade to a metal slide or Guarder frame (which IMO feels MUCH more authentic than the smooth glossy plasticky Marui frame).
Propane will put you at around 290-300 fps stock on semi. Can be upped to 330-340ish with high flow valves/hammer spring/steel hammer/nozzle valve/piston/tightbore barrel.
