My carry gun in 40 S&W is stuffed with Hydra-Shoks. Fortunately at this point I have no first hand knowledge of their effectiveness. They are highly rated however and that's why I carrry them.
As an aside I was born and raised in Massachusetts and IMO if you have a brain,and I expect you do if you post here, you should consider relocating. I was there about a month ago visiting relatives and felt like I was in a third world country.
