Hey guys. I just ordered a TM MEU which should be arriving in a few days. Already planning upgrades, but there are a few noobish things that I'm not sure about and couldn't glean from the 35 previous pages (lol yeah, I actually read them all).
First question. My current 1911 is a cheap CO2 clone so I'm not too knowledgeable about the other gas types. The answers I've found online sometimes contradict each other and I'd rather hear it from a community that knows what they're talking about. HFC134a seems pretty tough to get here in California, and from what I've read about R134a, it seems to be the same but without the lube. And most of the people here seem to prefer propane. So many different types! Will propane, HFC134a, and R134a(this one with 1 drop of oil every few mags) all work without any special adapters or add-ons? And can a stock MEU handle the extra force from propane?
Second question. When the MEU arrives, I was planning on trying to source a KM or PDI 6.04 mm inner barrel, but I read some pages back about a Tanio Koba Twist Barrel. If this is the goto barrel for ILLusion, would this be an optimal barrel for someone like me, who's just starting to get into airsoft customization?
Thanks! I have a ton of other stuff I want to ask, but will keep it in small doses
