varmintsinc, it will be used for indoor use. I think I'll end up going with a Streamlight TLR Light. I'm going to mount it anywhere from the 3 o'clock to 9 o'clock position, as I hold the weapon (3 o'clock would be mid right side, 9 o'clock would be mid left side). I'll have to figure that out when I get the light.
I've never used a weapon mounted light before so I'll have to see what feels best for me. I'm going to get one for one of my Glocks too.
Thanks for the help, NYH1.
