PLEASE NOTE: Gun sales in some areas have been impacted by government-mandated business closures. If your FFL dealer has been forced to close, has voluntarily closed or if your state has enacted restrictions affecting the transfer of firearms, you may not be able to complete your firearm transfer. You must contact your FFL dealer before ordering to ensure they are open for business and able to perform the transfer. While MidwayUSA continues to sell and ship firearms to all FFL dealers who are open for business if your FFL dealer is not open or is unwilling to accept your gun shipment, we may be forced to cancel your gun order.

The retail business environment is changing every day, in some cases hour by hour. MidwayUSA is doing its very best to get every order to our Customers quickly, while at the same time complying with all legal requirements. To ensure we operate within the law, we are having to change processes rapidly. We are very sorry for any inconvenience you may experience and assure you we will resume regular business operations as soon as possible. Thanks for your business and loyalty!
