Palmer's Pursuit Shop brass barrel is too small for pump handle
I just discovered and signed up for this forum. I'm very happy to see its existence as I am a new Sterling STP owner.
I recently purchased a 12" Palmer's Pursuit Shop brass barrel for the marker. I wanted something that would be both accurate and maintain the clean lines of the design. This barrel definitely meets those criteria, however the outer diameter of the barrel is much smaller than the inner diameter hole through the pump.
Does anyone have any suggestions how I can minimize the slop? Can someone make me some kind of sleeve to create a more snug fit? Is it possible to get a pump handle with a smaller hole? Is there a way to stabilize the pump arm?
