Fantastic job, Chris. Really spectacular. Thank you so much.
As for Incursion's comment: All critisims of this gun seem to come down to price... I have heard it all. "Oh yeah, well a cost that costs $1,000 should have X or shouldn't have X!" This is a high quality gun produced with expensive materials (no plastic, no cast or MIM parts -- instead stainless steel, aircraft aluminum, carbon fiber and Wolff springs) in a low volume factory with a lot of hand fitting.
Furthermore, there was ton of R&D that went into this gun. I can't recall if we have discussed this before, but Karl and Eric spent a lot of time and money working with Wolff and others to design the shortest possible slide/spring combination to permit reliable function. Much was trial and error, until they found the smallest combination that would contain 9mm pressures and function properly. The freebore issue is, I am sure, related to that. This is a design which absolutely pushes the envelope of gun design and the laws of physics! The reason its not .25 inches shorter is because its not possible -- can't reasonably be done.
Accept the R-9 for what it is. A sports car. A thoroughbred. A semi-custom handgun that pushes the limits of what is possible in a 9mm pocketgun.
Its not a target pistol, a race gun, a compact or even a sub-compact. It can only do what it can do. R9SCarry's results--I think--prove that it can do a lot. If bullet stability is your ultimate goal, a Glock 19 should do well for you. Or better yet, a Glock 34. Just don't expect them to fit in your pocket.
