My wife's SP101 .38 Spcl wears a pair of the Crimson Trace. I haven't put a set on my much bigger personal choice for house gun. I'm torn between that eternal choice of more guns and accessories for the one that I already have. Which one would I put a set on? Let's see, there's the P93, the Redhawk .44 mag, and the old Remington 870 12 Ga.--difficult choice!
