Below is from the law and epoxy is an option !
3. PERMANENTLY MODIFY TO 10 ROUNDS MAX CAPACITY. By December 10, 2018, permanently modify the non-compliant magazines so that they can accept no more than the legal maximum of ten (10) rounds. The modifications must be “permanent,” meaning they cannot be undone and the magazine is permanently limited to a maximum of ten (10) rounds (e.g., riveted, welded, epoxied, etc., and not restorable). If the magazines can be restored to a capacity above ten (10) rounds, then the magazines will NOT qualify as having been permanently modified, the exemption will not apply, and the owner will be subject to prosecution under the new law. An ammunition magazine which has been only temporarily blocked or modified from holding more than 10 rounds, as by a piece of wood or a pin or screw, is still unlawful.
