in the summer heat we carry a smaller, more concealable firearm.
I carry a S&W Model 642 snub nosed .38 in a pocket holster in my pants.

In the winter when it is actually cold enough to wear a jacket, I carry a S&W Model 60 .357 magnum with a 3" barrel in an IWB holster.

Obviously I am a wheel gunner but if you prefer semi-auto pistols you can find some very compact weapons to carry such as the .380 Ruger LCP.

or the 9mm Ruger LC9 which I haven't handled but I understand can still be carried as a pocket pistol.
