I have a 642 with CT’s older, textured polymer Lasergrip. It’s small, feels good in the hand and works beautifully. Their newest version is a more naturally molded polymer and rubber design for round-butted J-frames (hold the jokes, please). While I haven’t shot it yet, it felt awfully comfy to hold and you’d have to think the rubber grip will reduce felt recoil nicely . . .
