Stiffening the trigger on a Cooey Model 60

[762Russian]

Yeah, there's one you probably don't hear too often: 'My trigger is too light!'

Well, my old Cooey 60 has that problem; the trigger is stupid easy to pull. A stiff breeze could set it off. I don't have a measurement tool to give you an accurate pull rating, but if this thing is more than a pound of resistance I'd be surprised.

So, wiser folks than me, how would I go about upping the poundage on this old meatgun? I thought it was pretty sweet at first, having a trigger you can pull with a feather, but after some gopher time I've realized that this thing is genuinely dangerous, and not just in regards to small defenseless rodents.

Cheers,
Russian.

Before you play with springs check the condition of the trigger sear and hook on the bolt. They should be crisp and sharp where the trigger sear catches the bolt. Also they need to angle in such a way as to be slightly self locking rather than trying to wedge each other away. If they've rounded over with time and use then you need to correct those spots first.

Also check to see if some previous owner modified the trigger group to reduce the engagement amount between the sear and the bolt hook. In stock form the trigger is quite long and creepy. Adding an adjustment screw or simply sticking a little pad of something in place to reduce the engagement amount sharpens up the trigger a lot. But it's not hard to over do this sort of "improvement" and end up like your situation.

I found the same thing with my Cooey 600. Correcting and polishing the sear and bolt edge to correct the shape and smooth it provided a nice crisp release. I then added an engagement amount adjustment screw. Mine is now very light without being crazy light.

I have some Cooey sears/triggers.
