I'm glad Datan posted such clear photos of his R9 "after rework". I reported yesterday on my second range session (157 rounds cumulative total). My frame is wearing exactly like Datan's in the area below the rails, though mine shows no evidence of contact in that pocket.
My gun is serial #R360 and was delivered less than a month ago. It has the latest recoil assy with chamfer at front, radius on rear of barrel chamber, etc. I have to admit that I treated those heavy wear areas with
Brownell's Action Magic II before Super Lubing and reassembling. Probably won't make any difference, but
I feel better.
BTW: I've found an easy way to get the barrel pin back in during reassembly. I insert my Stop Stick up to the same mark as I use for disassembly. Then I ease the slide back a bit with a finger over the end of the barrel's muzzle until the assembly holes line up. With my third hand I can then drop the pin in easily.
Actually, I have the gun positioned so the pin drops in vertically & put the pin in the slide hole, then wiggle the slide back a little.
It's easier done than explained.
