We apologize for the substitution, given the changes in export reform we are no longer able to export magazines with an original capacity over 32 rounds. The PS90 30 round magazines were restricted to 5 rounds to comply with Canadian regulations and given there is only on design for that firearm the substitution was caught and made in the shipping dept, they should have reached out to you. We have now put checks in place to ensure that doesn't happen in the future.
I have also looked for your email but was unable to find it.
