http://www.lasermax.com/product.php?id=1 Is this any good? this is the guide rod laser in the ad box we see to the right all the time on GF Not inexpensive at $349 on special. I dont want a laser grip. Too thick grip. I see the usual rail mount jobs and wonder if this would be more accurate since its parallel to the bore axis and closer to it. I want it for my wife for a training aid. she is a new shooter. yes her hands are slowly getting stronger but she needs a lot of help I would say right now here group is something like 10-12 inches. and of course low and to the left Is it worth it? Opinions?
