I've just acquired a new to me rifle and I'm having some trouble finding information on it. It's a neat little 20 gauge over .22 mag with double triggers. You pull the rear trigger to cock the rifle and the front trigger to fire it. My perceived problem is the adjustable front trigger. It's so light, even after backing the screw all the way out, that just a light touch releases the hammer. When the screw is tightened, and I use that term lightly, the hammer will actually just barely catch as the rear trigger is pulled rearward and then release as the I let off said rear trigger. I know this is a high end combination gun, but I have no experience with these, and I'm wondering if this is normal. The gun looks like it was barely used if at all. Has anyone had any hands on time with a Heym adjustable trigger? Thanks in advance for your replies.
