Every gun owner should fire a crappy gun extensively for a year. Something that jams a lot. Something that breaks. Something picky about it's ammo and then don't use that ammo.
Why? To familiarize him or herself with a crappy gun. To get that experience. To do the failure drills.
It's frustrating, but valuable.
It will familiarize a person with how a gun works. It's a mechanical device. It operates a certain way. When it doesn't operate correctly you can figure out the way it was supposed to go, and internalize the corrective measure. Like learning the sweet spot on a clutch, and learning the optimal feel on when the engine says it's time to shift.
A reliable, works every time, pistol is a joy, but even these will have a breakage once in a blue moon. Second nature correctives are a nice thing to have in your wet ware, and if they don't fix the problem the long experience will give you a good idea on the true nature for further addressing on a gunsmith bench. Knowing at an instant "oh, I limp wristed it" "oh that was a light strike" "oh the magazine spring is going bad" or "oh an internal pin broke" is a useful thing.
