I think I read an article about it in the final issue of Combat Handguns a few months ago. Nothing wrong with a .380 except the ammo cost.
Even though in my book gel tests are far from penetrating flesh, muscle and bone of the human body.

In high quality defensive ammunition such as the Corbon DPX round, the muzzle energy differential from a 380 round to the 9mm+P is double.
Although, in the end I do like what firearms trainer Jeff Gonzales said, "In any fight, any hole is better than no hole; more holes are better than few holes; and bigger holes are better than smaller holes."
Plus, nowadays they are making 9mm handguns so small, single stacks like the Glock 43, the M&P Shield (not to mention Kahr having that market cornered for so long) make concealability no longer that big of an issue.
I'll have to go figure out how to post pics again, but in the meantime...
My carry varies. 1 or 2 of the following, M&P9 full size, compact or Shield, or G19. Depends on what I'm wearing and what I'm doing. My favorite is the one I have one me.
I recently got to try out the newer Sig P320 compact. That is a nice one to run too.
A number of you have some nice pics posted.
