**Note: On April 2, 2019, the city of Pittsburgh, PA passed a city ordinance banning the use of magazines in public spaces.  The ordinance includes a prohibition on sales of magazines over 10 rounds but due to state preemption laws, this section will not go into effect until such a ban is made permissible by the State Supreme Court or General Assembly.

These laws may change at any time and it is exclusively the customer's responsibility to understand and comply with the applicable legal regulations. Please contact Customer Support if you are attempting to complete a purchase under a qualified exemption (I.e. certain jurisdictions exempt law enforcement and military personnel from restrictions). 


  1. The case Duncan v. Becerra, (Case No.: 3-17-CV-1017-BEN-JLB) is currently active and focuses on the constitutionality of CA’s magazine ban. On March 29th a judge’s ruling allowed for sales of +10 magazines. However, effective April 5, 2019 (5:00 pm), the same judge issued a stay prohibiting ongoing sales of +10 magazines while the case is considered by the courts. The stay only applies to sales but keeps in place the earlier stay allowing possession of +10 magazines.

  2. Local laws are not included in this list if the state law is more restrictive.

  3. Overrides less restrictive municipal magazine limits (i.e., Chicago, Oak Park, Riverdale, etc.).
