You're talking about
me here and, in three decades of le experience, I've "rolled around" a couple or three times with a holstered Smith equipped with adjustable sights. On the one occasion that I had a part of a rear-sight blade snap off, I was at no disadvantage with the broken sight because, given the close proximity of the miscreant, if the revolver needed to be fired (fortunately, it didn't
),
any type of sight would have been about as useful as teats on a boar hog.
I think way too much is made of the supposed fragility of adjustable sights. As illustrated by the aforementioned instance, of the relatively few times in real life (police work or otherwise-the pistol being used in a military setting perhaps being the exception) that an adjustable sight gets damaged, most will get out of sorts in a close, hand-to-hand confrontation where a proper sight acquisition would be impractical, if not impossible.
