Yeah absolutely, they're called negligent discharges for a reason and I wouldn't personally hesitate to buy a Glock.

However, there is a distinction in that the essentially safetyless, essentially SAO trigger system is fundamental to the performance of the gun's function, whereas the takedown procedure is more of a peculiar wart of the design. So those idiots end up shooting their walls (and potentially other people) for no reason other than that Gaston Glock didn't want to compromise on the parts count. Typical engineer, I suppose.
