trigger problem

Hey ya'll,

I have quick question for you guys. I have a Lanber 2087 shotgun and the trigger is beating the living crap out of my finger. Every time I pull the trigger my finger slides across the trigger face and gets banged up. Specifically the bottom of the end of my trigger finger. It is quite painful and shooting doubles only hurts more.

I can't figure out what the heck is going on. I don't know if it's the fit of the gun, or if it's the trigger itself, or if it's just how I hold and shoot the gun. All I know is that this is the only gun that has ever done this for me and I hate it so much that I am contemplating selling this gun. Have you guys ever heard of a problem like the one I have and if so do you know how it was fixed. I really need to fix this problem because I can't even shoot 4 rounds of skeet comfortably and since I am going to start shooting registered soon this is a problem that I need to fix.

Thanks,
Jon
