I have the Crimson Trace on my M&P 340 J frame & there is a difference in the felt recoil w/ the shock absorbing rubber back strap vs. the solid metal of all of the other grips.The laser is a nice adition to the night sites as it is allways on the said target. In an emergency situation where you need to use your weapon to save your life it doesnt hurt to have as many advantages as you can . I practice shooting my CCW in all diferent manners, from the hip,on the fly ,point of aim,sites,& laser because when the time comes it is not going to be "perfect world situation" where you tell your target to stand still while I sight you in.
