I would be curious about groove diameter on these barrels.  If any of you cast and have the ability to slug the bore, please do so and post your results.

  I tried to drill a new hole in the Guide rod with no success.  I brought to a Gunsmith (parts changer) to have him drill the hole.  I also had him replace the Ambi safety and slug the bore. 

  I have not seen the slug yet, but he informed me over the phone that it was .400.  I'll have more info when I pick up the gun in a few days.

That makes sense , my RIA shoots the .401-200gr cast bullet from my Accurate 200G mould very nicely at 15 yards .

That is good to know about the groove diameter.  Still leaves the mystery of excessive copper fouling.

Scratch this!

I picked up the bore slug and it measures

.4035

I called Armscore and they are going to replace either the entire pistol or the barrel which ever come in first as they have no pistols or parts.  ETA is sometime in January.

If you have one of these pistols, could you slug the bore for me please.

A .4035 groove diameter would explain the heavy copper fouling.  Severe blow by of high pressure hot gas is the problem.  That gun needs a new barrel IMHO.

  Almost hard to believe.  That's insane.  Quality Control?....What Quality Control?  I'm very happy to see they are at least standing behind the product 100%.

dang, you guys are making me glad I didn't pick the one up at the LGS last weekend

Just a very quick add......Picked up mine on the 18th......Shot 2 mags right at dark......(I live in the boonies) ......Had a FTF (feed)..........In the next day (or two), I had time to fo 5 more mags........Long story short.......Had one or two FTF (feed) every other mag or so......Not a bad JAM, that takes alot to get stuff movinbg again , just didnt quite get a round in the pipe........Fast forward until today. My son and his family is here. He knows a lot more about 1911's than I....(And I'm not a total idiot).....We put another 4 mags thru the RIA 10 mm so he could see what HE thought was the problem......Well.....My problem isn't the ramp, etc.....He discovered and we tested it several shots. The FTF problem is because the SLIDE STOP (or slide lock) LEVER is engaging itself during mid-magazine firing......So we made SURE, we weren't anywhere near the slide lock dealy-bop and it still engages itself "every once in a while"......Just a kick pull back on slide (very small) and release makes everything OK again.....So now I need to find out which of the many small things that could be happening to make this occur.........I've said it before. This is a FINE trigger. Best I ever had from a semi lo-priced factory gun... I haven't checked that yet, but it can't be more than 3 lbs and a very short, smooth pull........One I get this side lock problem fixed, it will be my number one 10mil .......
Any idea's ??

Are you still running the weak 14lb factory recoil spring?  First thing I did was change mine to 20lb.

Yes, still have the factory spring. It IS light !  First thing my son said was, "Wow what is that spring ? About a 16 lb" ?  I told him I had read that they came with a 14 lb....He thought it seemed too light.......
Has anybody else had the slide lock engage on it's own before all the rounds have been fired ?

The type of jam you describe I encounter on my Para IF the cartridge overall length exceeds 1.250 with a wide variety of ammo.  Gun stops with a round partially chambered and is rectified by pulling the slide back about 1/8" and letting go.

Check the overall length of the ammo you are shooting.  Make a pile of the "short" stuff and and see if that ammo feeds ok.  Since I have started seating everything to 1.245" I have had zero issues with feeding.

Well I think I have the RIA 10 finally functioning . After having the case mouths on fired brass looking like someone took a hatchet to them I installed a 20# Wolf recoil spring. After firing 60 rounds yesterday no more shredded case mouths. I had talked to Sean at Armscor and he stated that a 20# spring and heavier mainspring were needed. He sent them off to me the day we talked. Still have to install the heavier mainspring and FBFPS I have sitting here.
I will say that I have NEVER had better customer service from any company. Armscor has so far offered to:
1. Pay for return shipping and repair whatever is wrong
2. Exchange for new gun if wanted
3. Refund purchase price
EAA needs to have their CS reps trained by Armscor and see how real customer service is achieved.

Pretty sure Tanfoglio buys all the frames and slides for their "standard" line from Armcorp already.  Maybe we could just cut out a couple of middle men
