$65-75 for a handgun in '53 sounds high, Looked up median US household income was only $4,410.
The reality is that good tools, and good firearms, have always been relatively expensive.
Only in recent times has there been good availability of inexpensive tools, and relatively inexpensive firearms.
I’m not that old, but if I think back to my youth there were no really cheap tools. Some were better than others, sure, but there was nothing cheap.
The problem now, is that a whole generation have got used to being able to source cheap tools. When they find good ones, at the price they have to be, folks think they are being ripped off!
Same with those handguns. The Colt’s / S &W’s being sold there are way higher quality than the most popular handguns being sold in the U.S. today.
