Thread: CZ doesn't shoot as well as I'd hoped

Any idea of what polyurethane/oil I could use that will match the current finish? It's a walnut American. Perhaps I shall lossen off the action screws and see what happens.

I think I can fit some paper down the channel but its tight, it is definitely touching all the way down.

I'd like to try any non destructive methods as to not ruin anything, but if I need to I will bed it/sand out the channel.
