Kevin, it is still listed on Iver Johnson's website ; https://iverjohnsonarms.com/store/c15/10mm.html ------------ I would check on large gun and accessory sites like (6)un (8)roker and Guns International as discontinued and hard to find firearms and accessories show up for sale by private individuals and small shops. Just replace (6) & (8) with G & B. --------------- Another excellent firearms website for searching is ------ gunsinternational.com/ -- Cheers and Happy Holidays!
