Well, you've got a good point. I started in Lim-10 but left because my equipment sucked. I jumped into Production, even though I thought the rules were stupid, and I enjoyed it a lot. It felt very "stock car" racy. Even playing field, and enjoyed it a lot. Turned out I was mostly wrong (some of the rules still suck a little).
I avoided revolver for a while (at the high end), because there actually is an equipment race. It just isn't purchased, its crafted in your own home. Tuning a revolver is much more important than you guys give it credit. I have a box/stock N frame in the safe with a 15 pound trigger.
It seems to me neither the rules nor the economics, support advancements for revolver. The subset of revolver shooters, shooting USPSA, is probably a tenth of a percent of total sales. Does the future look any better?
I don't see any demographics expert suggesting that revolver shooters want high tech advancements. Thats like titanium wheeled horse buggies. I see it as we are such a small demographic that anyone spending research money on technical advancements would be throwing away good money.
The next technical advancement I see is a spring loaded cylinder that ejects the moonclips automatically.
