The laser grip is quite a bit smaller and lighter than the rubber grip. The pistol weighs 13.5 oz with the Hogue and 13oz with the laser. Also the laser grip is more concealable and doesn't grab at your cloths like the Hogue. The recoil absorption between the two is similar also. The biggest attribute IMO is the laser itself. If your looking for a wood grip I`d say its only a matter of time.
I am not sure if we are talking about the same thing but, the LCR uses a grip stud (I believe that is what they call it), so it will aways have a stip of grip material over the back of the grip. The grip is not made the same way as a S&W.
I belive the "grip stud" is just Hogue's thing, look at there Ruger Single action grips they use it also but the Factory grips have the screw that go through the center so I am sure something is possible for the LCR.
