i put grease on it but i was a wimpy weak kid who struggled to pull it, even with grease on it lol. now i took it out a few weeks back when cleaning some space up and find it quite easy to pull now.It needs good grease. I got some good trailer grease at TSC, and I grease when needed with a paintbrush, usually every two weeks. And I strip the gun every 2-3 months and wipe it all off and put a new layer on.
