As I said before a coach gun is a tool, and will work just fine IMO in 99% of self defense situations. However my opinion is predicated on the fact that I have never offended any colombian drug dealers, I do not frequent or have gang members as guests in my home, I dont know any Ninja's, I have no reason to expect that my gated community will be runover by hordes of disinfranchised Obama supporters, I cant think of anything I may be doing to invite Dog the bounty hunter to my home, I cant see why i would be targeted by 10 man tactical home invasion teams bent on getting the $200. cash I keep.
Coach guns will work quite well I believe on
Two or three junkies trying to steal my flat screen while I'm home.
