Ive uploaded a new photo and hope this is better

You will notice that there is a lighter area on the sear (looks like a reflection from a flash, but its not). and on the other side there isn't a reflection. This what I'm concerned about, that the sear is only wearing on one side. Would this be an indicaiton that the hammer hooks are not at a 90angle, or the hammer is faulty...

I'm finishing a build on a Bullseye gun and the trigger is not great, and the only thing thats not match quality is the hammer.

I cleaned up your picture the best I could, I have never seen a sear worn like that, its almost llike it's contacting the hammer on an angle.

Any chance of a clear picture of the hammer ?

Thank you for taking the time to "Clean up the photo" and I will be able to take a better photos this weekend. I'll try taking a photo of the hammer this evening, the quality may not be there.

I thought the wear was odd, and it likely explains the poor trigger pull I'm feeling.

I can't see anything in the photo, but if you are getting burnishing on only one side of the sear it means that it is not mating correctly with the hammer hooks. Try marking the sear face with a black magic marker and assemble the gun (without oil on the hammer or sear) to see what kind of rub marks you get when you cycle the trigger a few times. The sear face should be stoned to mate the hooks pretty much exactly. If it isn't, you might want to have a smith look at it. Improper fit here can lead to the gun doubling or worse.
 
The engagement cut across the hammer doesn't look straight or clean. The sear reflects this. I would suggest that they need to be refitted or replaced.

Agreed. It also appears that the half-#### has been hitting the sear on the way down, mangling it there as well. I don't know if the hammer and sear have enough meat left on them for a proper re-fit, but the best solution; replace both parts (and probably the disconnecter) and get a competent person to set it up for you. Fire control is not something you want to mess around with.
 
Better pics.

I suggest replacing both the hammer and sear.

The sear has dragged on the hammer but it is worn on the engagement edge.

Aslo the pin holes may not be straight too.
 
Just checked the Brownells catalogue. They list a number of hammer/sear sets that are pre-fitted and ready for final installation. I think that would be the easiest fix.
 
Everyone - thank you for the quick replies. I figured something was up when I saw the wear and the trigger pull was not great even. I've ordered some new a new sear, disconnector and hammer - and a set of new pins.

I'll post a follow up message when things are working.

I'm going to need a good pistol smith in the Ottawa area or Toronto. i know Gunnar is highly respected, but I'm hoping not to have the gun away for a few weeks.

Thanks

+1 on the pin holes, they may either be out of alignment or they could be oversize. Who is the manufacturer of the gun ?
 
I bought a norinco as a base, and have been building it into a Bullseye gun using Fusion Firearms parts. They seem to be good quality and not MIM.
 
I agree with having a a knowledgable person work on the trigger is what I will do. Sending it to Gunnar, vs Dark, or another well known gunsmith in the local area is likely wiser for me for me from a time perspective as I am planning to compete with this gun in early june.

brian if you dont have a jig to check the hammer and sear you can always use the frame itself. Remove the hammer and sear,lay the gun on its side. Place the hammer and sear on the outside of the gun. Using the pins to locate the parts you can now see the sear engagement. there may have been to much taken of the sear and its hiting the safety notch. You should be able to see that.
 
All fusion parts are machined bar stock. I was thinking of getting a trigger group from them.

Brian, how was the trigger pull before the parts wore out, and how many rounds before wearing out?
