These laser grips are great. I put them on in a few minutes. Had a little trouble getting the pin all the way in but that is due to the grips fitting tightly for accuracy as they should. Once on I manually adjusted the windage using the manual sights and the laser dot (without firing). Then it was off to the range. I was sighted in a few inches high, but after a few turns of the allen wrench the sights were dead on. This is one of the best investments I have ever made with relation to fire arms. Not only is the sight easy to use, it really helps you getting used to point shooting and lining up the target quickly without having to worry about the sight picture.
Pros: Easy to setup, adjustable sights, very accurate
Cons: changes grip feel just slightly
