"BTW co2 pistols dont need to be maintained anymore then a regular green gas pistol. With my experience they work perfectly fine before and after everytime i use them and i treat them no different then my green gas pistol."
This is incorrect in almost every way, CO2 has no lubrication put into it, making it the driest gas, which means you should be lubing it after every two weeks or so, if not then o-rings dry up and slides stick, etc.
Unless you regularly maintain your gun when it's on green gas that is.

Well i guess your buying some cheap pistols because everyone that i have ever used and own have never had a problem with them. And i currently have 4 co2 pistols and 2 gas pistols and they all work fine and i do nothing to them
