offrdmania:
What if you pull the barrel and the recoil rod out of the slide? Try that and see if the empty slide moves along the frame just as tight or if it smooths out with these items removed. It will help eliminate areas to consider.
JMH:
Great suggestion offrdmania! Thank you. Your idea was a springboard to a new way to look at the problem. I did as you suggested and without the assembly and barrel, the slide is smooth as can be. So, I put only the barrel back in and held the R9 upside down to help keep the barrel flush with the top of the slide. I was able to replicate the problem with only the barrel in place. But I don't see anything that might cause the barrel to impair slide travel. So while I feel like I am closer to understanding what is going on, I am not able to explain why it is happening. Anyone recall anything similar? All contributions much appreciated. At this point I would be happy to discover the fix and have a working R9 and a big red spot on my forehead from my palm hitting me in the head.
offrdmania:
Take a look at where the barrel rubs against the underside of the slide when you rack it, as seen below. You can see the rub marks on the top of the barrel. A lot of times this edge on the slide gets marred up causing too much material to grind against the top of the barrel. Have you greased up this point or put some oil on it to lessen the friction?
JMH:
Great photo offrdmania! Serious macro lens. I do not see any wear on my barrel or slide but with fewer than 100 rounds fired it might not be readily visible. I did measure and the slide travels about 5mm before the barrel 'hits' something very solid. At this point I can just see the left edge of the hole in the frame where the roll pin is inserted. Do you think the barrel is supposed to move out of the way somehow? At least now I know barrel in=problem, barrel out=smooth slide motion.
MRC:
Is the pin inserted through the barrel lug correctly?
What I am talking about does it go through the hole that cams the barrel down.
