I have the .380 BG and I can carry it with anything on, shorts and T, dress slacks, etc.
Carries nice in a pocket holster, and is easy to 'present' if required.
Carries easy on the ankle (any weight there can really present problems if spending much time walking etc) and I have relatively small hands so I don't even use the finger-hook mag base, so it doesn't 'print' at all.
Also, 'disapears' in a small on the waist cross-carry holster under a partially open shirt and therfore easy to access when seated (driving/out to dinner).
Obviously, not the biggest caliber in the bunch, but at 5-10 feet (most likely deployment) I would suspect that it can get the job done, and you'll likely have it with you.
I used it in a IDPA 'bug' match and it was easy to shoot one handed, and just about as easy to speed reload as a full size auto.
I'm diggin' it!
Good luck with your decision, and Semper Fi
