1911's - Western Arms
M9 - Tokyo Marui
Sig - Tokyo Marui
Glock - KSC/KWA
Supposedly, the KSC/KWA USP is good too, but I've heard mixed reviews on it. Some people like it, others have a lot of problems with them. Definitely better than the KJW USP, though. The KJW and HFC M9's are pretty good too, being direct knockoffs of the TM ones. If anything goes wrong, any upgrade part for a TM will work on the KJW or HFC. The TM/KJW/HFC Glocks work extremely well too, but are less popular than the KSC/KWA Glocks.
If you want a good beater gun, the KSC/KWA Glocks are probably the best bet. The TM M9's are super reliable too. Hate how they feel in hand, though. Too bulky. I, personally, favor the single stack WA SCW2 1911's. I'm currently eyeballing that WA MARSOC model with the scalloped grips. (Yeah, nobody likes them but me. Helps you keep a good grip when you've got sweaty hands.) I've found that I don't like any of the WA pistols with the old Magna gas system. They're very tempermental in extreme temperatures. The SCW2 system seems much less affected by ambient temperature.
All gas pistols can take 134a or green gas, depending on the ambient temperature. To generically say that one gun can take a type of gas, but another can't, is wrong. Gasses have different pressures at different temperatures. When they hit atmosphere, they expand and that's what pushes the bb forward, as well as moves the slide back. Here's a chart from Snowman's site about gas pressures...
