I'm going to ordering a set of LG-405's from S&W for my 340M&P and had a question about how to properly sight them in. I've read that you should sight them in by aligning the laser dot so its right above the gun's front sight is this correct? If they are sighted in this way what yardage are they sighted in to? Also do these laser grips use two batteries or one? Doesn't one of the grip panels hols extra batteries?
