I know some gun stores have them. I was looking for one from a fellow site member. I just joined and I was unaware of the 50 posts rule until a few hours ago. I'm working on it.
IMHO, a 9MM is sufficiently defensive for the problems I expect to ever encounter. If a bigger gun is really necessary, it's probably some place I don't want to go anyway.
Got mine for $375 new. Pre-panic of course.
