Is 144a the right stuff for a TM 5-7

[bobthebuilder]

Tried to search, but since five, seven and gas are all mega common words, it doesn't like it, so I may well have missed something.

Basically, I've got a TM Five-seven on the way, and I know I can't run it on my current gas (Green gas, spesifically Zero one top gas)
I'm trying to work out what I need to get instead, and Abbey Predator 144a comes up. Is this the right stuff? or do I need to keep looking?

144a would be fine.

I've heard that Abbey Ultra (aka Z1 Pro Gas) is the best for TM plastic pistols.

I've heard that Abbey Ultra (aka Z1 Pro Gas) is the best for TM plastic pistols.

By all accounts the 5-7 isn't quite as robust as the glocks, 1911s etc. running it on high power gasses can cause issues.

Most TM pistols are happy with Pro Gas/ Abbey Ultra, the FN57 is the exception. Supposedly even 144a can harm them in very hot weather, so definitely no higher than that unless very cold. I would recommend a better outer barrel, and permanently attaching the slide rails to the BBU. After that, Green Gas is ok.
