Moshin, yes it is Maryland compliant without the 12 round magazine. Buds will remove the magazine but won't replace it. During checkout there will be an option to remove the magazine. You would have to purchase state compliant 10 round magazines separately. Here's a link to a 10 round magazine if interested. Hope this helps, link here................. budsgunshop.com/product_info.php/products_id/135852/ruger+90713+oem+9mm+luger+ruger+max-9+10rd+nickel+detachable+magazine

Yes, it is good to go for MD except for the 12 round magazine's which Bud's will remove. You can purchase your state compliant mags at this link below.
