Mossberg 590 Bolt Disassembly?

[Wanta B]

Hey all,

Have any of you taken the bolt assembly completely down? My new 590 has a sticky bolt lock and I would like to polish the sides and pin hole but can not seem to push the pin out...I did not want to break it so did some searching after it didn't come out with minor punch and hammer plows.Rumor has it that the pin is slightly larger in the middle to prevent it's falling out?

Thanks
Wanta B
