If you think there's a wide variety of handguns to choose from these days, wait until you get a load of all the holsters and retention systems folks have devised for carrying them. While it's not possible to review every option on the market, here is an introduction to some of the more common holster types available.
Pocket carry is a popular self-defense choice since it is one of the most inconspicuous ways to go armed. However, just dropping a small semi-auto or revolver into a pants pocket or a purse is a bad idea. The gun is likely to become scratched and dirty, and small objects like keys or coins could become entangled with the trigger. A good pocket holster will protect the gun and keep the grip properly oriented. Most pocket holsters are simple and affordable. Good examples of the breed include the Uncle Mike's Sidekick (Left) for small semi-autos, and the Tuff Products Pocket Roo (Right) for J-Frame revolvers.
