Man.......how light do you want to be on a "major" caliber pocket gun??? The Ruger LCR 38+p weighs 13.5oz unloaded......the S&W442 and S&W642 weigh in at 15oz. Each carry 38+p which is a more effective round than 380. I don't get it........ At some point you reach a point of diminishing returns. As the handgun gets smaller and lighter it becomes even more difficult to shoot accurately and the recoil can become quite painful. Sure, I can shoot a small gun ok but stout recoil does not make for long practice sessions. I mostly carry 45acp pistols. But when I have to wear a tucked shirt I go to my Ruger LCR for pocket carry or my Glock 26. I've carried the Glock in my pocket (does well in Dockers and cargo shorts), and IWB (both tucked and untucked). At slightly over an inch in thickness the Glock conceals easily under a tucked shirt. Galco, High Noon, and others make perfectly functional tuckable holsters.
