Wow, a lot of Sig lovers on this thread. I handled a Sig .380 at a Gun Shop not too long ago and I instantly felt an attraction, but I can't stand paying the price for one of those. Especially, when I can get a Glock for half the price. (Don't ya just love the Military/Law Enforcement Discount Pricing Glock has?)
So, I actually have a Taurus .380 and a Kel-Tech .380. Both have had mods done to them and the Kel Tech kicked bad before I wore it in a little. The reason why I prefer it though to the others because of the belt clip that you can attach on the back part of the frame. It makes for AMAZING conceal carry.. I wore it to the batting cages, out throwing the ball around and even jogging. I am also a small frame girl (120lbs) and it can be tough to find something that is easy to conceal and will stay put!
(If you get the clip that attaches, I reccommend wearing a tank top underneath.)
