Up close, the .380 should get the job done. A sawed-off 9mm, the .380 is certainly a better alternative than a .32 or .25 or .22 I bought a used Kel-Tec and I like the ease of carry when the weather is hot. Try lugging a Model 639 at the beach. I can't wait to see S&Ws version of the Kel-Tec/Ruger LCP/Kahr/etc.
