Here is a set of used Crimson Trace Lasergrips LG-308 that I received in a trade. Midway USA lists these grips for $299. I am asking $175 shipped. Per new rules post "I'll take it" in the ad followed by a PM. Payment by USPS money order. Here is a list of the models these grips fit:

K- and L-Frame Round Butt Smith & Wesson Models 10 through 19, 48, 53, 56, 64 through 68, 242, 386, 396, 547, 581, 586, 617, 647, 648, 686 and 696.
