That's just not true. I DO however agree with a lot of your last post.And profit is profit. Sure, more profit is better, but if Colt made one dollar profit on each revolver sold they would not have stopped making them.
USFA up until very recently made a seriously great, top notch single action revolver. One that in all respects is even nicer than the Colt SAA. They sold every one they made with people waiting in order to get one.
They sold at a premium price. They could probably ask whatever price they wanted. Some costing multiple thousands of dollars. People were willing to pay the price to get one.
They stopped making them in order to focus on a new plastic .22.
There are tons of reasons businesses do what they do. Profit is clearly one of the main reasons, but so is loopy/misguided management along with a host of other reasons.
Colt simply chose to focus their resources on other things. S&W quit making single action revolvers likely for similar reasons
