I have the 3-inch LCRx in 357 Mag. It has a bit larger grip, and more weight. Makes for an enjoyable shooting experience with 38 Special ammo.
I've seen a couple of the shorty LCRs that the owner purchased the larger grip that comes with the 3-inch model and installed that grip on the shorty LCR. It gives up some concealability, but makes it easier to control, more comfortable.
^^^^^THIS, you can get the longer grip through Hogue^^^^^^^^^^^^^^^^
