The question has been asked quite a number of times, usually after a cop drops his piece or forgets to flush it. Unfortunately the vast number of euphemisms for "dropping a deuce" obviate an effective search for these questioning threads.
I CCW'd for about ten years in SC. About half of those years I carried Mexican Chihuahua style, after my IWB holster failed.
I dropped my H&K USPc .40 into the crotch of my skivvies. That way it was still accessible but discretely hidden and not likely forgotten.
