Ok , some answers. No, I do not have any sales statistics for Mini sales. And yes, I am basing my "life support" comments simply on my observations at the range, matches, and what I see going out the doors at local shops, and the huge support market catering to the AR. So yes, it is conjecture. A question posed for comment. Because, though I believe all gun sales are still up a bit, the AR family is likely outselling Minis by a wide margin. And since Ruger is making and selling AR type piston rifles, why bother with the Mini? Two platforms for the same purpose. I'm betting they can the Mini. 5-10 yrs. max.
Regards .308 Mini. Ruger tried, they called it the XGI. It did not make production, though a few factory examples are about. I saw one on Gunbroker about 10 years ago. R.L. WILSON's book "Ruger and His Guns" discusses it and has some pics.
Regards a correction officer with a Mini. Yeah, lots of agencies went to the mini as a patrol rifle when they first came out. Priced against the AR at the time, they were a bargain. And the wood and steel look was conservative/PC. But many agencies have moved away from the mini, ( my outfit did, over 20 yrs ago!) I much doubt very many mini's have bought the rifle new to arm a dept or agency recently (again conjecture). So many vets these days (bless'em) familiar with the AR, why issue a throwback design. (odd safety, take down, etc.)
Hey, I like'em, I like their relatives, but I fear their days are numbered.
