I have a Mossy 500 High Rib Trap gun with a trigger assembly that has broken ears. Where can I get and affordable metal replacement?
 
'eBay has some listings for complete trigger assemblies'

I have been told that the trap model has a different trigger assembly.
 
Besides Numnuts (Numrich/GunParts Corp), call Jack First too.

One fellow's exit exam at TSJC included assembling a dozen of those trigger groups. He failed and had to return to retake the test.

I'm not seeing anything on the drawing that remotely resembles an 'ear' though.

Yes, I have. They have the plastic trigger guard assembly, but I am looking for a metal aftermarket assembly if I can find one reasonable. I think I need a need a bolt too. Sometimes, it leaves an empty in the chamber upon racking. It could be just the spring or extractor, but I am going to replace the whole bolt given its age. I will post pictures of the broken ears Wednesday when I have more time.
 
Sounds like you need new extractors, pretty cheap fix. No need to replace the bolt due to age, that's why they made them out of steel.

As far as your trigger housing, Mossberg has not offered the metal ones for over 10 years. Just get a plastic one and replace the guts.
 
From Mossberg Today:
The extractors can be reviewed on the Mossberg web site under the Model 500 schematic.
The trigger group is not sold separately. The gun would need to be sent into our service center for evaluation. The price would be quoted. It runs around $145.00

They are only slightly different - the trap model trigger assy is missing a small crosspin (in the hammer I think?) that releases the slide bar when the hammer drops. I bought a 500AT second hand years ago for hunting without knowing better, and having to depress that release button every time drove me nuts until I learned it was deliberately made that way. Mossberg would not sell me the trigger assembly but I was able to make my own pin to 'fix' it. Not sure about removing that same pin in a standard trigger housing to make it a trap trigger but I don't imagine it would be a huge problem.
 
Without take the tigger assembly part, it appears the the trigger pin has a cam lobe to lower the front of the release mechanism to allow the slide action to work freely without manual assistance. Also, the bolt does not have a locking lug spring; it this suppose to be this way for a more speedy action when engaging the clays?

I bought the gun, from a pawnshop, a few years ago for my nephew when he was on the high-school trap team. His parents have since then bought him a Stoger and a Browning 725 pro model. Needless to say, the gun has come back to me...
