I don't know if it's worth the cost to put one on my LCP. I mean it's a back-up/pocket gun. Is a laser going to make any difference, really? I highly doubt it...
Besides, it looks like the activation pad would make holding an already small gun with a 2-finger grip that much harder.
I don't own any lasergrips, but if I did it would be for my Ultra Carry II. However, I still don't think a laser should ever replace a good set of night sights. I guess I can see how it might be useful for training purposes since it easily lets you see how steady your aim is.
Also, I notice that some people who like them say it's because their eyes are going bad. If you can't see your target with regular sights, how is a tiny red dot going to help you? Maybe laser eye surgery is what you really need!
If lasergrips were under $150 then they might be worth buying. But the price they are charging for them is completely insane! You can buy a very nice gun for the cost of two sets of lasergrips...
