Franklin, guessing you're referring to the (ships free SMG) on firearm pictures. If so it means (ship my gun). It's a firearms shipping company. If interested here's a link to their website. Hope this helps, link here............... Shipmygun.com

Franklin, SMG = Sub Machine Gun, a magazine-fed, automatic carbine designed to fire handgun cartridges. There are SMG semi-autos for civilians. In Bud's listings, SMG means Sub Machine Gun-size semi-automatic pistol, such as this budsgunshop.com/product_info.php/products_id/154142/lwrc+smg-45+.45+acp+black+pistol .....Have a great day!

Hi Franklin, it is a synonym of ShipMyGun (SMG). It is essentially a firearm shipping service for us common folk. Details here : shipmygun.com/go/ ----- Cheers and stay safe!
