My constant carry is a 360PD AirLite usually AISW.
The super light weight and form factor make it effortless to carry. Shooting it can be a painful operation so I bought a 340 Pro Series all stainless to shoot.
When I bought it I immediately took it out to my backyard range and it locked up tight after the first round. New out of the box failure on a weapon I thought would never fail to fire. Turns out that a tiny metal chip had got into the works and locked it up.
Taking the side plate off and blowing it out fixed the problem but it somewhat unervered me as to revolver's as never fail weapons.
When practical I'll also carry one of my 3rd gen autos. My 4040PD as first choice, but a 3914DAO for it's small size and thinness.
