As noted above,, the current market is focused a LOT on the tupperware types of firearms. Throw in the covid excuses,, the shortages of raw materials, the shortage of deliveries of materials, and the fact that it's cheaper & easier to make & sell tupperware,, many models of firearms are on the back burner.
Ruger is in the market to make money,, and if they can sell 100,000 of tupperware products,, vs 20,000 SA revolvers,, with the profit margin much better on the tupperware,, guess what will be made & sold.
Besides,, they, as well as many others,, suffer from employee shortages due to the whole covid thing. Ruger,, as well as many other gun makers did not even have a booth at the industry SHOT Show,, because of covid.
Hard to build products when people are out sick, or told to stay home if exposed to covid.
So,, you have to HUNT for many models of guns that have been made,, and will be made again,, if things get back to "normal". Because currently,, many are not available.
