Coleman MAX tail cap?

[Don't Laze Me Bro]

Hey guys, Well I had a bit of a problem with my coleman MAX PHR, I dropped it by accident, and now the tail cap will not work proper, WHen I click it, the laser powers on only when I have it pressed half way down, as soon as I let it go it turns off any ideas what is wrong, or if I can fix it?

thanks all,
Dustin
