These look like factory issued grips. They do add a little width to the grip area but I have big hands so this is a plus for me. Installation is a snap. 4 screws to remove old grip panels and 4 screws to tighten these on the pistol. If you can't make it to the range after installing your new CTG just use the little hex wrench and move the red dot to match your iron sights. I did this, went to the range, and I was dead on at 15 yards with my 9mm. I've had the LG 402 on my weapon for over a year now and it looks like new.
Pros: Activation, installation, bright red dot.
