Actually, thats a big maybe.
Ive been carrying a second, unloaded Glock around the house, for pretty much every minute Im home, everyday for over a year now, just stuck in my waistband, or in a pocket, or doing pretty much everything youre constantly told you should not be doing with one, even picking it up by the trigger, and so far, have yet to ever have the trigger tripped, other than intentionally pulling it.
Not saying it cant happen, but unless you do something really stupid, its looking to be just an overblown "scary" thing.
