I have early Endomags that won't feed anything but round nose ammo.
Looks like the bullet is fed too high.
Have you made changes to the feed ramps or angle since the first generation?

That is not something we hear often - we run hollow points through Endomags constantly.  Please reach out to our support department at [email protected] or 404-889-8960 and we will make sure you get everything running.  Endomags are definitely covered by our Lifetime Warranty so we will fix or replace them to make sure they're running correctly for you.

Any sort of "speed" loaders available for converted mags?
I have some set up for use in PCC, and having to load quickly between stages doesn't seem all that quick/easy.

When they first came out, people with the CMMG RDB's were advised to just cut off the fixed ejector.
Like the ones shown on the left.  The ones on the right have like 'wings' that go over the rounds to help guide them. That is what I run in mine.

Is there a speed loader for the 9mm endomags?

Unfortunately, not right now.  We have tinkered with modifying a Caldwell MAG Charger with mixed results.

Mine IS a RDB and using 1st gen Endomags.

I modified a ETS Universal Rife MAG Loader and it works perfectly. I just put rounds in plastic trays and pick them up ten at a time. Works similar to stripper clips.

Basically, I just cut away material so that it lined up with where the 9mm are seated. Did this last year sometime and have no issues. I don't have an image hosting account so unfortunately, I cannot post the pics.

A mag loader such as that pictured below should suffice:

That particular magazine loading aid/tool was an Olympic Arms (OA) product.  As OA went out of business in early 2020, buying from them is no longer possible.  That said, I do not know who made the tool as OA did, in fact, use outside sources for some of the parts and accessories that they sold, while making "major components" (OA's terminology) in house.

In any case, perhaps you could prevail upon MEAN into producing or outsourcing such a tool or similar as there is no real inventive work/engineering expense needed.  Just a few measurements and tooling.  As I don't have and do not ever intend to have Endomags, I have no interest and only provided the photo as a service to the ARFCOM community.
Best of luck.
MHO, YMMV, etc.  Be well.

Appreciate the response.  
I currently have an ETS type inbound to see if it meets my needs.
I'm not going to hold my breath that MEAN will be of any help.

@amphibian to the rescue! Thanks for posting pics.

My three are the 1st gen with the factory ejector delete.
Besides the "wings" (feed lip extensions?), the feed ramp angle seems less steep.
When mine malfunctions, it's the rounds hitting high on the chamber mouth.

@MEAN_Arms, should I dig them all up to be sent back?
They were ordered directly.

How many 9mm rounds fit into a 30 round AR mag using the Endomag?
