If anything killed it, it was marketing. Marketing would forecast what the consumer market wanted and what was on hand. They would then schedule the production. This was what I was told when I used to take the Ruger Armourers' schools at the factory.
The volume was probably not there to justify the production set up costs. More money could be had in making other things. Businesses are there to make money, not lose it.
Vigilantibus et non dormientibus jura subveniunt. Molon Labe!
