Midland Backpack trigger work

[Bcturkeynut]

Helped a buddy setup a Midland Backpack 20ga single-shot for his turkey gun.  The pull on the trigger is 7.25#.  Would like to get it down in the 3.5# range.  Has anyone else had trigger work done on this model gun?  If so, who was the gunsmith and how was the trigger after the work on it?  Thanks
