Here's some at Brownell's that are designed especially for the Benelli... but some are for the synthetic stock.. I
think the others are for the walnut versions..
IF so, (and a quick call to them will give you the answer) those for the walnut stocks are easily replaceable by you and require no other gunsmith intervention..
