I've recently noticed that people have been referencing the Gunslinger's mini-sentry with the fact that it regenerates HP.
What is this regeneration of HP? I know many players regard the Gunslinger as an extremely OP weapon, but I don't understand how it fully works. Can someone explain how the Gunslinger works completely?

To clarify, because it hasn't been given as an answer yet, the 'gunslinger' itself, the weapon that you use that allows you to build Mini-Sentries, does not have an HP-regen ability. It grants you additional HP, guarantees a crit on a third consecutive hit, and does not random crit, but the item itself has no further special properties.
Formerly, the Mini-Sentries that a Gunslinger could build would always deploy at full health. This had the unintended side-effect that was likely what the SPUD user was referring to - a mini-sentry in the process of being built would constantly regenerate its health until it finished building, making it nearly impossible to destroy before it finished deploying (unlike normal sentries, which can very easily be destroyed before they finish their initial building animation).
This has since been patched out, so that mini-sentries no longer infinitely regenerate health while being built.
