Beretta, Remington, Smith & Wesson, have all moved to Dixie.
Colt which is now owned by CZ and Ruger are about the only ones that are still based in New England. All the others have moved or are newer companies that were always based elsewhere.
“Ruger are about the only ones that are still based in New England.”
Bill Ruger probably had the intention of moving the headquarters to Prescott AZ. It didn’t happen in his lifetime but the pistols are made here in Prescott and the local governments have an open invitation for Ruger to move here.
Sig is still up North.
