Hi guys... I am looking to purchase a new light for my G19. I have a Glock model light but don't like how the end of the light is adjustable to tighten the beam. It always comes loose and doesn't hold. I am looking for a tight,bright beam. What I am looking at is the Procyon,WX150 or the TLR-1 C4. Does any one have any pictures of these lights mounted and even better a picture of the beam or throw of the light...any help would be appreciated.
