As a relative newbie to 1911's, what are some of the trouble areas or weakness of the 1911's that I should be paying attention to?

Consensus seems to say that 1911's require more attention to maintenance, etc compare to striker fired polymer pistols. Please enlighten me.

Some background info regarding my question was due to dinner discussion with a friend who stated that his $500 Glock is more reliable than 1911's.

I was thinking if compare to similiar price point 1911's, he's probably right but once you move up to the $1,000 to $1,200 price range you would be getting a more reliable 1911 by comparison but don't have enough self knowledge to say. Only from what I've search from the internet.

Thanks for all the feedback and help!
