Hi All: I am looking for a tactical light that I can basically "click" onto my Glock 23 Gen4. I don't like having a tac light on my glock all the time. I have favorite iwb holsters etc that wont fit it and i like my 23 better without. However, i would like to have a light and click it onto the gun when its sitting next to my bed or when i open carry while walking the dog or something. any suggestions? thanks!
