I have a Bodyguard, but don't have anything against the Ruger... as suggested, shoot both. Also as suggested, the .380 you have with you is better than the .357 you left at home.
I will throw this out there.... here's a Bodyguard .380 compared to a Sig P365 in 9mm:
The P365 is wider and heavier, but the overall size is about the same. 6+1 of .380 vs. 10+1 of 9mm.
My Bodyguard only comes out of the safe very rarely, and only for when the smallest possible profile is necessary and when pocket carry is the only option. Most of the time, the P365 gets the nod.
