Eh, I don't think it's a bad pistol. I like the revolver better but, I also think that they do no justice to the original bodyguards and am a little disappointed in Smith and Wesson's lack of creativity to come up with a new name for a new line of firearms.
I HAD the BG .380. Notice I said HAD. I fired 25 rounds thru it and the trigger would not reset. Sent it back to S&W, got it back, trigger STILL would not reset. Finally after working 50+ rounds thru it the trigger would reset MOST of the time. So much for S&W service. Took it back to the LGS I bought it at and traded it for a Ruger MkIII. Ended up getting a PF9 to replace the BG .380.
All that said, when it did function correctly it was a nice shooting pistol IMO. It fit my hand MUCH better than the LCP which I never felt I had a good grip on. I really liked the BG .380 but the problems I had and the many others were just too much for me. I haven't kept up on it but I assume S&W has ironed out all the problems by now.
As far as the .380 being too whimpy for PD, THAT one I'll NEVER understand. I've seen what some of the HP .380's can do to "stuff". Don't know about others, but I would NOT want to be hit with a .380 HP, let alone several.
A BODYGUARD has a humpback and a hammer! What was S&W thinking!
