Over on the shotgunworld forum, it seems they are somewhat tolerant of the use of "shottie", but there was a post there back in 2006 about just this subject. (http://www.shotgunworld.com/bbs/view...=72079&start=0
) Feelings there were basically the same as the OP's.
It comes down to common vernacular. "Pic" and "gators" are common vernacular; "shottie" is not (yet).
