Yep, the ones that work the hammer/firing pin. If you look at your forend you will see how the mainspring trips the ejector lock in the forend. These mainsprings have to be the correct length. If the mainspring on the offending barrel was replaced, perhaps the gunsmith didn't check the length and fit as necessary.
