Thanks very much for the link.
I tried swapping out the extractor with the one from the 1900 Parts Gun, and am still concerned about the looseness.
I did check to be sure the peg was seated into the hole when I changed them out, and it still seems loose.
You're right, this is no shooter, but if I ever want to take it for Show and Brag to a gun show, and they plastic wire tie the action open, it actually looks like it could work its way loose and fall out.
Any ideas on the right side leaf spring rattling?
None of the others do this.
Edit to add:
Thought of an easy solution to the gun show dilemma.
I'll just get it a trigger lock to "show safe" when wandering around the aisles with it.
