I was cleaning mine the other day and had a pucker moment when the pin dropped and I thought it was gonna go down the drain. I was think, if I did lose it, it's such a simple unimportant part that I would probably just go get the right gauge stainless steal rod and make one out of it. I hope Mossberg was able to get you what you need, but from what I've read their customer service isn't the best and it's hard to find replacement OEM parts.
