HK's won't be made because HK holds their brand pretty close to the chest. GSG pretty much got a cease and desist letter.

They do make 9mm AR15's. You just have to look for them. Several different companies make them.

On the HK note though, you can still have an HKMP5 semiauto... I just had one built on an original HK parts kit.



Now, it's waiting on SBR paperwork so I can put a stock on it.

Any Glock 9mm can use the easily-available 31- or 33-shot factory-made G18 magazine to get what you want.

Here is my G26 with the 31-shot magazine in place:



Much lighter and more portable than most (all?) of the weapons you listed above, and very easy to shoot well.
You might end up with a cramp in your trigger finger before you are through, though...

glock also has 22rds or 24 rds with extended floor plate for its 40 cal

You could always get a Hera for a G19/17
