My original idea for the light was to add some rail on the under side of the handle area. While screwing around I noticed my light fit in the channel so I figured I try it out. This will be modified some more but works well for now.The light in the channel is a great idea! It seems to me there is a lot of space beneath the carry handle that Kel-Tec could utilize as well, perhaps they could find a way to mount a light there. Any issues with having the red dot on top of the handle? Seems to me that might be to far above the barrel and it gives the weapon a high profile.
I also thought the dot was too high, perhaps it is if you are going for distance. The longest hall in my house is 25' and is zeroed accordingly. No real need to aim at 10' or less so I feel good about where the dot is set. I can get on target fast and adjust if needed.
