Does anyone know where 10 round magazines for Model 4006 can be purchased? I ordered what was advertised as 10 round Magazines for the 4006 and upon arrival of these magazines from two different sources found them labeled 4006/410 and they are too short by about 1" to fit the 4006. Hawaii like a few other states restricts magazines to 10 round. Could a magazine carrying more than 10 rounds be legally modified to limit it to 10? Any information would be most appreciated....Aloha
