I have the CT Laser Grips on my K9. They are good for training. You can put the laser on the target and watch it go way the heck off as you jerk the trigger. I see a lot of that at the range... especially with the long gun .22's! So, pistols are even harder to hold on target. It really is a good training aid. I don't want the polymer pistol ones, though. They are UGLY and add awkwardness to gripping the pistol, especially if you don't want the danged things ON. Ever notice in a movie how you can see those from anywhere else in the area... leading back to the shooter! At least, that's more of a problem with the Laser Grip models... illumination of your trigger finger and the right side of the pistol... or being blocked by your trigger finger along the frame!
Yes, they could be helpful for firing from the hip as you dive for cover... maybe... if you aren't yanking the trigger too much. Adrenalin rush and heat of "battle" don't make you the best trigger "squeezer" and Murphy can be counted on to "help" you.
All that said, my night-sighted and laser-gripped K9 is my TV chair at-hand weapon for night confrontations. If I have time, I'll grab my "battle pistol" XD45 with HD NS and 13+1 + a whole bunch of 13-round mags... and a "tactical light".
I just don't like them, but others may. Just train with what you carry and make sure everything works.
