Interesting you mentioned this as I have a K100 I am looking to get milled for an RDS for this division right now.
All arguments aside, I am looking forward to this division because it sounds like fun. I don't shoot USPSA to enhance my tacticool skills, I shoot for fun. In order to be interesting for me a new division has to offer something that the other divisions don't. Production I view as the basic division. Limited gets you major PF and all sorts of fun gun crap. Open gives the dot and a comp. Each of these has some very fundamental differences from each other. I like production optics because it provides something that is fundamentally different from production. Yes, you get to shoot the dot in open, but there is a WORLD of difference between production + dot and open. I think this could be a very interesting hybridization of open and production that keeps the essential skills from production (accuracy, reloads, stage planning) while being different enough to remain a compelling choice.
On a side note - if anyone knows a smith/company that will mill a K100 please PM me...
