This is not an uncommon story for firearm manufacturers unfortunately. Tooling costs are high, sales hard to predict, and designs can fail easily. Ian McCollum of Forgotten Weapons has done a lot of videos on this topic.
Like there's a lot of discussion about usage and practicality among gun enthusiasts, but when they buy their 3rd or 6th gun ... I suspect the decisions are more about difficult to predict things and whims.
It is a strange market.
