My wife bought a 642 and the first thing we did was add CT grips.

She can out shoot me using most any gun with regular sights, but the short sight radius of the snubbies is not conducive to quick and accurate fire for the even best marksman.

The CT's are just one more tool in utilizing a tough to shoot little sidearm in less than optimum circumstances.

My "night time" gun is a 1911 with tritium night sights AND CT grips.

I also wear a belt and suspenders!!
