I like to carry my NAA Black Widow in 22mag. It has a 2" barrel. Sure, it is not as powerful as my 40S&W, but it fits in my shorts pocket and no one ever knows I am carrying it. Dry phone bullets are penetrated 4-5". I think that is enough to do the job if the shot is well placed. Also, I have never had a single failure with this gun with many types of ammo. I have shot many armidillos, one shot one kill every time.
I definitely will look at the Hornady 45gr ammo. Right now I use the 45gr Winchester Dynapoint. I might chronograph it this weekend and post back.
