Well, because I'm 6'3" and about 240, I don't have any trouble hiding a full size pistol. And because I wear suspenders, I don't care what it weighs, so my 4" 686 Smith is an easy all day carry.
The load isn't an exotic, or expensive load, it a Remington 125 grain JHP. Remington says its about 1500fps and that oughta do it.
I make my own holsters and on a hot day I carry in a pancake, and when it's cooler an iwb.
In the 70s, and 80s I worked narcotics in this 3 county area where I live, on the Oklahoma border, so I carry wherever I go.
