I have not had both but I have a BG380 and I used to own the LC9. I did not care for the LC9 trigger was horrible but was meant to be that way, I do not like the loaded round indicator, although a lot of people do like it. I don't like the plastic guide rod and did not like the feel in my hand. It also has a magazine safety which I did not like. If you think S&W 380 had recalls, look up the LCP on Google for problems especially on the Ruger sights.
The BG380 is a perfect pocket gun in my opinion. It is very comfortable in the hand, SS guide rod comes stock on it. No magazine safety, I like the laser on the BG, The BG comes straight out of the box perfect, no complaints No problems, flawless.
Get the BG380
By the way the BG380 will never be sold. The Ruger just could not force myself to like it and I have always been a big Ruger fan. I love thier P90's and Mark series of pistols.
