I love them on my 1911. They take much less practice to become proficent with (but still do take some practice). For those that have tried other types of lasers, there is not much of a comparison, the laser grips are the best. Normal holsters fit, no extra switches to activate (normal grip pressure will turn it on when you grab the gun) and if you don't want the laser on for a particular situation, you can easily not activate the laser with your grip (great design!!).
Never tried them....but, I have tried other laser aiming devices. Don't care for them.
Sights are faster and more accurate.

I will admit that some of the fastest shooters with irons MAY even be faster with them than they are with lasers, BUT I also have a few other points to bring up....
Are you saying that there is NOT A SINGLE situation where having a laser aiming device would be beneficial?? (not able to bring gun into eye line, due to injury or obstruction, aiming around corners, very low light situations) They may be unusual, but they do happen.
Also how much time have you practiced using your iron sites? where you instantly an expert with them? then why do you expect to be instantly so good with the laser? it is a TOTALLY DIFFERENT AIMING DEVICE. Yet you instantly claim irons to be "faster and more accurate". Take 1/10 of the time you have practiced with irons practicing with a GOOD laser (cheaper ones don't hold zero and ARE pretty useless). I'd bet you see a much faster learning curve for the laser.
Given the same amount of practice with laser and irons, I'd bet on the laser being faster every time for that person....
I'm not saying give up or stop with the irons, just pointing out that the laser is another good tool to have in your bag, and can help you close the gap in shooting skill for those that don't constantly train (probably most of us).
