Connecticut was the heart of American gun making...
Was, Colt? Smith and Wesson maybe? Ruger?
Springfield arms was in Taxacheusetts.
Glock I believe is Hq’ed in Georgia, and AIM and Inter Ord were in Virginia AFAIK.
I think it is a sign how out of whack the Several States are when the homes of the Revolutionary War volunteers are now the locus of 2nd amendment disregarding.
