Approx the same amount of weight is still there, the bulk is still there, just relocated. A alloy, double action, J frame holds 5-38 spec, 6 32 H&R mags or 7 22 mags. They weigh in at about 10 oz and they are easy to reload. They also have trigger guards and a grip designed for a human hand. They are also available in hammerless models. I believe you would be hard pressed to find a spot you could carry that concealed and not a J frame. The BIG PLUS, with the J there is no fiddling around. Grab it, aim, fire. No fiddling around opening the handle, cocking and TRYING to aim it.
Interesting? Yes, but so were those little wheels kids were spinning in their fingers.
