Of the revolvers I own, ......
.... None of them have a wedge spring which interferes in any way with the removal of the from the barrel lug as far as the screw on the port side of the barrel.
When the wedge clears the arbor freeing the barrel for removal, the spring engages the screw in a way that prevents the wedge from comig completely out of the barrel.
About half of the times it does not work and the wedge winds up in my hand to be placed aside unitl I put the barrel back together.
