I am not so much of a gun aficionado that I have a stellar collection of firearms, a to-die-for (no pun intended) handgun that I am salivating over or a monthly subscription to every firearm magazine on the market. What I do have is a small collection of weapons to meet just about every conceivable need that may arise.
For concealed carry, I am particularly fond of the Kel-Tec P3AT. In my everyday work I don't need heavy duty firepower, something that can withstand heavy duty use or state-of-the-art materials. What I do need is a reliable handgun that shoots cleanly, is reasonably well made and ultra concealable so I can put it in a briefcase or conceal it easily under my clothes no matter the weather. The P3AT fits all of these needs. Chambered in .380, this little handgun (check out the picture--it's only slightly bigger than a pack of playing cards) has a solid feel, smooth trigger pull and is actually pretty accurate. The only "negatives" I would report are related to the size of the handgun--if you have really big hands you may find this uncomfortable to shoot or draw very quickly and, also due to its size, this isn't a gun you are going to want to practice with every day. However, the trade-offs are more than worth it as it meets the need for its intended use--concealment and having a dependable weapon on hand for what, to date, has been the exceedingly rare emergency.
Whatever you decide to carry, if you decide to carry, make sure you are picking a weapon based on your own needs. The most expensive, biggest or most popular weapon may not be at all what you actually need and rather than being a blessing could turn out to be a curse.
