Assuming you have to pick a pistol knowing that you will have no access to professional maintenance in the future (e.g. a disaster / "dystopia" scenario), so the thing should just WORK w/o being revised by any gunmaker or other professional for many years and thousands of rounds - what making would you choose?
Get a few maintenance parts, and a "Glock Armorer's Tool". Do it yourself.
In a dystopian scenario I don't know where you'd be getting "thousands of rounds" over "many years".
