Point taken, but pretty good chance that a blown cap isn't too great at holding a charge anymore.

And if the capacitor wasn't blown but it was instead a seized motor or something?

Then why are you replacing the cap?

General debugging of hardware might lead to that.

Regardless .. discharge the cap, blown or not.

Clear the chamber, even if you removed the magazine and checked it yesterday.

etc.

The general principles of health and safety are intended to be largely overkill and mostly not strictly required, they're in place for that one time that kills or injures.

Just don’t lick it haha
