Of course a large part of the .380 ammo shortage is due to the ammo manufacturers being shortsighted on what the demand would be. The other reason there is a shortage of .380 is because it is the hottest craze in CCW arms right now. I guess those 2 reasons are really kind of the same. It is debatable if the attention towards .380 is deserved. However, the newest batch of .380's are smaller than the 9's. 9's got smaller, so .380's got even smaller and lighter. Comparing 9 to .380 probably isn't even relevant anymore. Because of the carry-ability of this new batch of guns, the comparison is really to the .32's and .25's that were previously found in guns that size. In that comparison, .380 is a hands down winner.
I wish I could get a LCP, or a Kel-Tec in CA, but we need a few more elections to work on that. I do already have a S&W .380 that works pretty well, other than the awkward magazine release - The Sigma .380.
