Winchester model 12 ejectors
 

Not about a double gun so if this is wrong spot or not allowed on page I will gladly delete but didn’t really see other spot to post thread appropriately. However I recently purchased a Winchester model 12 20g at Tulsa gunshow but negligent of me did not pay attention to see if it had an ejector till tried it when got home and wouldn’t eject and come to find out it doesn’t have one…looking to purchase a replacement online but wondering if all gauges had the same size ejector or if were certain gauge/gauge set specific?

Regular 12 - 16 and 20-gauge M12 ejectors are all the same.
12-gauge Heavy Duck Gun (3-inch) is specific though a regular ejector can be modified
28-gauge is specific

Thank you sir! That’s what I had been reading on internet so far but wanted to double check with the trusted, knowledgeable people of this group. I’ll be ordering one soon.
