When I purchased my 1999 Mossberg 500 I found it extremely difficult to remove the trigger group. This, I found, was because the mainspring retaining pin had moved from it's hole and was catching on the stock. Pushing the pin back into place resolved the issue. Until Sunday's four rounds of clays, that is. Same issue, same fix.
While the pin is not symmetrical, this is in keeping with other Mossberg 500's I've seen, and the pin does not appear damaged. Mossberg customer support recommended sending the trigger group in, which I suspect would end up with me being charged for a new trigger group. What's going on with this thing, and how do I fix it?
