I was told 45 or bust.
that article is 4 years old. I wonder if there are any new offerings since then.
My edc is a .380 S&W Body Guard. The .380 Federal Hydra-Shok Deep sounds very interesting. I will have to utalize some Google-fu and see what I can find on it. Currently using .380 Gloden Sabre. My wife also uses her 380 for her carry gun and has hers loaded with the same Golden Sabre.
