So I'm new to the whole laser thing, so I've got a couple of questions… I see a lot of the lasers mounted on the top rail, in front of a pressure pad for a light. Do you recommend having a pad with a constant on feature? Currently, I have the Modbutton and Modbutton lite on my guns. Also, I haven't seen any images with the laser mounted at the three or 9 o'clock positions. It looks like it might be a little bulky to mount there. And if I were to mount it at 6 o'clock, would it be way too much to operate the pressure pad for the light and the switch for the laser? Seems like it could be a bit of a juggling act.
