Simplest solution to stoppages: Carry a revolver.
Seriously . . . I agree with both of you. Stoppages, just like constipation, will happen sometimes, despite the efforts all knowledgeable shooters take to prevent them. Practice clearing stoppages should always be part of the practice drill; it's darn near as important as being able to hit the target. A pistol with a jammed cartridge suddenly becomes little but a rather awkward club unless the stoppage can be cleared quickly. I too use the dummy cartridge routine to practice.
