Offset primer strikes are only an issue if the primers don't go "pop", IMHO.  Same with primer flow as long as the load is in spec, there are no other signs of pressure, and you aren't seeing reliability issues.

My issue with mine is it doesn't run reliably.  Granted I have only put two magazines through it, but in 32 rounds I had at least fifteen 3-point jams.  Gonna look at the extractor and dress it up and try again.  If it still won't run, I will send it back to RIA.
try polishing the breach face with flitz or other low abrasive polish--- don't take any material off of the breach face, but do polish it so the case will slide up the face easier---I tweaked my extractor a bit loser to help but didn't want to go too lose, so I polished the face and it now has no issues feeding at all (I would get 1 or 2 where the case would catch on the extractor and hit the hood for a mis-feed before this)  I also just dressed the "claw edge" of the extractor so it wouldn't "bit" into the case--mine wasn't too bad, but it would jam once or twice per magazine --- as far as the off-set primer strike, I'm not to concerned as like you say- as long as they go pop and my accuracy is not affected by it

I'm probably going to spend $15-20 on a few springs just to play around to see if they do anything--if no changes then I'll stick with the stock set-up and pull the trigger

I had the same 6" Pro Match for a while. Honestly it ran pretty well except for the slide stop locking back prematurely. Did some filing and it pretty much went away. My problem was I couldn't get it to group. They sent me a replacement gun that appeared a little better finished, it shot good groups and ran really well. Between it, 2 other 10mm 1911's and a 1006 I decided to whittle it down to 1 1911. Trying to work up a good load for that many different chambers is difficult. Some are better than others depending on how you look at it but each one has it's own limits on how much pressure it'll take w/out messing up the brass. I've gotten split cases out of one chamber where the same load would be fine in another. Smiles out of guns that aren't supposed to. Primers falling out with one gun but not even showing pressure signs in another.

The Rock was actually pretty good but I didn't really shoot it enough before I sold all the 1911's to get a custom longslide built. Now I only have it and the 1006 and I don't really shoot the Smith very often. I've had primer flow but I figured it had more to do w/the composition of the primer material than overpressure as the primer wasn't flat to the edges. I still backed off the load though, just in case :)

Im happy with the accuracy from mine, it can shoot far more accurate than i can. I have never had an issue with the slide locking or with the ambi safety getting in the way of my trigger finger as a few others have stated. The gun fits my hands very well.

The flow&shear problem may be a blessing in disguise as it definitely let's you know your upper pressure limits by looking for that "gold ring" rather than trying to decipher if the edges are flat yet or not. I've never had that issue with any pistol I have ever owned though so it's got my anal retentive tinkering personality wanting to fix what may not be broke...i like perfection and this doesn't seem to be perfect to me.

That crushed brass issue....the extractor isn't holding the brass tight enough for the ejector to do it's job, and as a result the brass gets crushed against the barrel hood before popping out of the way.



Your friend can probably fix this himself in about 10 minutes by watching a youtube video about extractor adjustment.

Thanks sqlbullet, your pics are exactly what is happening with his pistol. The piece of brass on the far right in your photo is what all his damaged cases look like. He won't try and fix it himself so his pistol went back to RIA yesterday.
