Will it fit Ruger sp101 model — 1 Answer

This product is intended for use with the Ruger LCR only.

All is not lost - Crimson Trace makes two models of their LaserGrips for the Ruger SP-101

LG-111 is a polymer (hard plastic) grip,

while the LG-303 is a rubber overmold that is a bit longer than the LG-111.

The Crimson Trace activates when you grasp the grip firmly. In a self defense situation, fine motor skills (like pushing s tiny button) deteriorate quickly. Gross motor skills (like grasping your gun) still function.

LaserGrips also have the advantage of being compatible with most, if not all of your existing holsters, while trigger guard lasers require a new holster for the specific holster/handgun combination.
