This is something you aren’t going to see often. Another series of photos of some custom gunsmithing history. This is a never used extended safety made and sold by A. Swenson. Courtesy of our pal Karl Beining , custom gunsmith extraordinaire. www.KGBcustom.com. Karl has had this in his own collection and refused to let me have it.
Swenson started out making these by hand but later had them produced out of casting. This is one of those later “mass produced” type safeties if your keen eye detected signs of casting, you are correct.
