Jam session

A few questions:
Is it new? If so, did you field strip it and wipe off the RIDICULOUS amount of lubricant RIA ships these with? I assume you would, but just had to ask. If not, did you field strip it and inspect/clean it thoroughly? That ramp doesn't seem to have seen much use, so I'm guessing new. Again, just had to ask.

What kind of ammo were you using, if more than one type/brand did any feed better or worse than the otheres? I have the same pistol and just put ~ 100 rounds of RNFP 180 grain (all LAX Ammunition) through it with nary a hiccup other than the slide not going fully into battery after the very first round. A sharp rap with the palm of my hand solved that.

How bad do you want/need a DS 1911 in 10 mm? RIA are a very affordable, reliable (usually) entry into this market that are built on solid, albeit heavy, frames. Nearly everyone on this forum has more experience in these matters than me, but RIA frames have a reputation here for being worthy of being a good base for a custom build. It might be worth sinking a few bucks into fixing the feed issue, it'll probably be less expensive than moving up to another DS 1911 10 mm platform.

Just my 2 cents.

I'm guilty! I ran it right out of the box. I'm going to clean it and I've had pretty good results from polishing feed ramps so I'll get back to you all. Hear is pic of scratch on round that jammed in pistol. the scratch is from sharp edge of feed ramp.
P.S. IT is Sellier & Bellot 180gr. FMJ.

Your pistol; do as you want, but it only takes a minute to look at the extractor with the slide off!

Need a loaded round sitting on the breech face with the rim under the extractor. The hook should have a sliver of daylight between it and the rim?! Does the front of the hook make contact with the bevel ahead of the rim—if it does, no good?! There should be enough tension on the wall (inside of the hook end of the extractor) against the rim to hold it in place if you turn it upside down and wave it a little?!
Does the extractor sit square in relation to the slide and breech, or is it clocked?! Is there brass accumulating on the chamfered edges of the extractor?!
Take a look at some of the extractor threads that have been posted by Theraptur, Ruffdup, and Steve in Allentown—they will have examples, and links to Steve’s Extractor Tune.
What you are describing, I’ve seen with out of tune extractors. You can polish the bejeesus out of the feed ramp and you’ll only get the ramp out of spec. It looks like a mirror already from your photos. I’d eliminate an extractor issue first. Just did this rodeo with my Tisas Service Model which was nose diving. First thought would be the ramp, but it had nothing to do with it. The rim couldn’t slide up onto the breech face, and the slide had no where else to push it but down!

Here ya go! It does hold a loaded round while I shake it.

Is the hook bottomed out / touching brass in the groove of the rim (fig.1), or is the wall / inside portion of the extractor pushing against the out side edge of the rim, as should be the case (fig. 2)?
Sorry for the primitive drawings, but I can’t take detailed enough photos to illustrate this. Theraptur has a good photo of what a proper extractor looks like right now on another thread. The pressure on the cartridge needs to be against the rim, and not the hook pressing against the bottom of the groove—if this makes sense?
The actual hook should have a sliver of air around it—shouldn’t be touching anything by a few thousandths. Only the outside edge of the rim should make contact with the Wall / Inside portion of the extractor.

P.S. go to Gunsmithing and Troubleshooting and find Theraptur’s “Another Extractor Tuning Example.”
He’s got really good photos of what your extractor should, and should not, look like.
Would really like to see you get that 10mm running like a sewing machine!
