Ok, so I see the Angstadt and CMMG versions in the SI store. Assuming I choose to abandon the FA Uzi, which AR 9mm is the way to go?

Thanks! Thinking add a SB brace and sighting options and it would be good to go.

Not technically an AR, but I love my Sig MPX. Has almost the same layout as an AR, only drawback is not using glock mags lol. Extremely accurate and a robust platform.

If I were to get a glock compatible platform, I would agree with Gabe. The cmmg looks nice from what I have seen as well.

Not to hijack a thread here, but I have a 9mm AR question. Is the forward assist less important on a 9mm than it is on a rifle caliber AR? Why or why not?

I would argue that a FA isn't that important on a properly built 5.56 AR either. It was an afterthought by the infinitely wise US Army leadership cause they thought it would help stuck cases get seated into the chamber. In fact, if you have a problem that requires a forward assist, you have much bigger problems at hand than the forward assist can really solve.

Other question: Why buy a 9mm AR when you could build a Glock PDW?

There are advantages to each system.

i built a 16" 9mm carbine about 15 years
ago, as a match/range training platform &
I still like it. About 10 years ago, I built a matching
7" 9mm pistol. I have shot them a lot & still
like them, but as I see it now, the SI PDW is
the end of that road.

My initial thoughts:

AR pros:



AR manual of arms
Many common parts to full sized ARs (triggers, optic mounts, etc)
Longer barrel
Less expensive

Glock PDW pros:

Shorter, more compact
Can be broken down into a handgun size
Compatible with all glock parts
EDIT: More easily operated with one hand?



Anything I'm missing?

mine...actually an article in progress

Actually the cost is the same unless its a ghetto home built on bargain parts...I suppose one could put an RMR on a high Point as well but hardly the focus here. The Size is about the same, but for 90% of those buying a PDW Glock, it is a part time application. I consider it a part time application if it does not have a cominolli safety. The AR-9 (and understand I am referring to a quality weapon with quality components and an optic) is a little easier to hit point targets with and at distance with. The lines blur, but a pistol that has been modified to work in the rifle/smg realm is not as good in that realm as a dedicated rifle/smg.


Glock PDW pros:

Shorter, more compact


If organized properly the size is not as much of an issue as some might think.




Can be broken down into a handgun size


That...the Pseudo-NPE application is why most people opt for it. A man with a CCW is a common thing, whereas a man carrying a rifle is not. But a man with a CCW with a Glock PDW brace in his briefcase is easily overlooked.



Compatible with all glock parts
EDIT: More easily operated with one hand?


Not really.




Lets NOT fall into the trap of the "one weapon that does everything" mentality. There are situations that a PDW Glock is a better choice and a time when an AR-9 is a better choice. But we need to qualify what is desirable in an AR-9 because not all of them are equal and not all worth a damn.

That's a good summary to me.

I have built a few glock 9mm ARs. All of the lowers that I tried had lrbho. None of the were consistently reliable on holding the bolt open on all of my mags

After rebuilding my last one, I finally got it where I want it.....i think. The biggest change I made to it was using a new frontier armory side charging upper with lrbho. The lrbho on the upper has worked 100% on every mag I have (glock, ets, magpul, even have a couple cheap Korean ones I got for free) the side charging handle helps cut back on gas to the face when suppressed. I also added a heavy buffers 12.5 oz buffer and it helps with the gas slightly also.

One major difference between the 9mm AR and the Glock PDW is cost of entry into the highly modular Glock PDW. Adding a 9mm AR to the battery means buying a new gun. Adding a brace to a Glock you already have is a low threshold buy-in. Spend that first $100 and you quickly realize the value of the full system, it starts you on the same R&D path that Gabe took to its logical conclusion.

A 9mm Angstadt is GTG as soon as you mount the sights, it already has a safety and easily manipulated mag release. IMO adding a brace to a Glock, even one with an RMR, won't get you the same level of functionality until you add the safety and extended mag release.
