I've found that a .380 carried 100% of the time when I am not naked or asleep beats the heck out of a 10mm never carried because it can't be concealed or carried without a major rig.
My wife has what may have been *THE* last of the purple Kel-Tec P32's, and after carrying an MK9 long enough to not like it, I've come to the dark side and and am carrying a KT P3AT, parkerized in OD green, and loving that it disappears and rides unnoticed in any garb I care to wear, from tux to speedo and all in between.
Good onya, jj!
