We hi-capa magazine mantainice

First off 95 % of my searches are done via iPhone, my home pc is crap so if this has been posted please tell me or link me to the post

My question is
Bnib what do I do to maintain the hi-capa magazines? (hi-capa 3.8 meu)

Loaded my mag twice no problems, upon third load heard a hissing sound and gun failed to fire the last 5+ rounds, magazine was extremely cold after the third time.
I'm using propane

Like I said up front please direct me to the thread/post if this has been asked before

seem to found adding a few drops of silicon before each use has corrected my issue so far is there any else i should do?

The terms you used, "hi-capa" and "meu" are contradictions. It's either a double stack hicapa or a single stack 1911 MEU.
