I think all of us there could agree that the problem is a combination of gun-issues, ammo-issues and shooter-issues - in *that* order. Failure to maintain per Rohrbaugh recommendations is *not* the problem. Incursion field stripped, cleaned and lubed his gun very carefully and well within the suggested shots-fired range.
Shooter-issues:
Incursion had continuous problems with his gun. He rarely got through a single mag without a problem of some sort.
However, he shot my R-9S extensively and only had one failure. On that failure, he turned around as soon as it happened and said something to the effect of "I think I pulled that one or limp-wristed it". To his credit, he immediately took responsibility when he thought that he might have been the cause of the problem.
I had zero problems with my gun, shooting either FMJ or JHP. When I shot Incursion's R-9, I experienced one FTX. Also, the mag released and dropped into my palm a couple of times. This has *never* happened on my pistol.
I was surprised at the amount and variety of failures that we experienced with Incursion's R-9. Failures which we, including Incursion, did not experience with mine. This is *not* primarily a shooter-issue.
Ammo-issues:
Incursion's R-9 shot more reliably with Blazer FMJ than it did with Gold Dot JHP.
The ejection of Gold Dots was problematic on basically every shot. What Incursion hasn't mentioned is that when his pistol *did* eject the GDs, it tossed the cases straight back into his face. He had multiple strikes to his safety glasses and even had a couple of minor cuts on his forehead (with blood!) by the time we were done. Blazer cases were ejected better, but we still saw some FTX issues.
His GDs shot reliably in my R-9, with multiple shooters, including Incursion. We didn't run any Blazer through mine. (I just don't like the stuff.)
Gun-isues:
1) Lots of FTX. It looked like the extractor claw was "bouncing" over the case rim, chewing it up in the process. I don't know why, but Incursions R-9 is not able to reliably extract the case from the chamber.
2) Some FTE. Not the classic stovepipe. As far as I can recall, every FTE looked the same. The cases were pointing forward, in-line with the barrel, caught between the rear edge of the slide ejection port and the rear edge of the chamber. The case rim was chewed up the same. It looked like the FTEs were FTXs that got a little further - but didn't beat the slide.
3) Mag releasing. Weird. At first, we blamed it on Incursions shooting grip (thought he might be tea-cup gripping - nope). Then we blamed it on his gloves. Pulled them off and it still kept happening.
4) Guide rod. We couldn't beleive what we were seeing. After taking my gun apart, it was clear that the disk end of the guide rod, which butts up to the lug on the bottom of the barrel, is both screwed and welded. The welding broke and the smaller rod came out the front. At this point, we were done with his R-9.
After all of this, I was a little nervous about letting him shoot my gun extensively... Wouldn't you be? :-) We decided to do it anyway. He ran 10 mags through it with a variety of ammo with only the one problem, which he thinks is likely his fault.
More later. SWMBO is getting antsy to get errands done.
Buh-bye!
