We have one LCR in our family (wife's carry gun) and I'm planning on getting another (for myself) but I don't see a need for an exposed hammer on what is basically a small, lightweight, concealed carry, short range, defensive gun. An exposed hammer could snag or accidentally cock, and thus cause a safety issue, especially in a gun that lends itself to pocket carry, inside waist carry.....
I view this newest LCR is a step by Ruger to eventually offer a full size, open hammer revolver with the LCR trigger group. Actually an LCR with a 4 inch to 6 inch barrel would be something I could see myself getting. The current closed hammer LCR (especially in .38spl) in my opinion, is one of the best snubbies to come along ever. I really like the trigger system, the light weight, and the way it absorbs recoil. I grew up on the great S&W revolvers and have shot / carried most from the Chief Specials up through the 686. I prefer the LCR over the Chief Special.
TO RUGER: Please make a 4" open hammer using the LCR trigger group and make it in.45 Colt!
