My Airmax Dominator - 44 shot string.

Maybe you could do a little smash on the side of the pin by the top end to create a bulge that would make a interference fit?

It is threaded together so the blue locktight will work good on it with no need to swedge anything.  The polymer handle spins on the part that threads on, actually a decent design IMO.
