That's an interesting idea, and it makes mechanical sense. I really wonder, though, how realistic it is. Given how much pressure it takes to pull the trigger (overcoming the striker spring at its most compressed, compressing the striker block plunger against its spring, and the friction of the sear sliding off the striker under tension) and given the fairly small mass of the stamped trigger bar, could the sear actually be released this way even if the gun were to achieve terminal velocity and land squarely on the back of the slide on a concrete surface? Has it ever been tried? Or is it a lawyer mandated design feature to satisfy some import requirement or an imagined legal scenario?

I'm almost tempted to go down and see if I can get the sear to release by pounding the back of the slide on my workbench with the trigger safety taped out of the way and (of course) the gun unloaded. But I'd rather not abuse my gun that way.
