S&W makes a rival to the LCR. It is called 38 Bodyguard. Comes with a lazer built into the frame. Rated for +P which is what I prefer. The weight is 14.3 oz.

My experience with moon clips. I have a Taurus 805 which is a 40S&W revolver. It uses moon clips, (they call em stellar clips or some nonsense).
They do not hold the bullets as firmly as a speed loader, so pocket carry can dislodge them. On my gun if they are not in perfect position it can jam up the wheel. S&W made a pistol chambered in 9mm, (model 940), that used moon clips. It was soon discontinued.
