Co2 guns are short lived. I would stay away from Co2 GBBs pistols. If you don't believe me start calling major retailers and ask their tech guys, not their salesmen. They are kinda like the "Lipo ready" gimmick for AEGs. I have run my TM on CO2 and HPA but between 70-130PSI (air rig) which is a huge difference from unregulated gas. I have also upgraded the piss out of it. Why can't you use propane/ green gas or red gas? And yes, it'll be cheaper just to get another $30 holster.
If you are insisting on CO2 I would consider asking these questions on the GBB forums besides here. They would know more about Co2 and pistols and what it takes to keep them skirmish-able enough to see a return on the cost in upgrades, if thats even possible. You could also just say you love airsoft, spurge and we'll understand while you run late on your bills.
An external air rig and a small Co2 bottle would be cheaper than a new replica and you could convert the mags you already have. I would use fittings that have the same threads as your mag's fill valves. Take the fittings out in spring and reinstall the fill valves. On top of that, you have an air rig which are a piece of cake to sell if you don't want it for other projects. I walk my velocity up to 400FPS (315 w/ .3g) in my 1911 and can shoot out to 200' with it. Its pretty awesome. 350FPS is still great but we allow 0 MED for 400FPS in semi-auto which still really hurts, but eh, paintball was worse.
