I would agree with most of the above posts. It is defantly possible to pocket carry but I find it a tad too big personally. I have a bodyguard .380 that I wear as a backup and occasionally if I'm lazy or running the dog out I'll throw it in a pocket holster and it disappears. The LC9 IMO is better suited for iwb carry. You can pocket carry it of you are larger framed and wear loose pants with big pockets. It's a weird size, just above being small like a mouse gun, but still too small to get a good solid grip on (I have big hands) but my fiancée has baby hands and she can shoot the tar out of it.
I just pulled the fiancée's LC9 out to give a comparison(sorry for the horrible pic quality) It's a S&W Bodyguard .380, a LC9, and an XD .40 subcompact. For pocket carry I would personally recomend considering a LCP if you are really wanting a Ruger or the Bodyguard .380. I absolutely love mine, it hides extremely well in a pocket or ankle rig, I half forget it's there half the time.
