This German publication, DWJ, (which I can't read and haven't had the chance to look at with Google Translate) contains photos of what appears to be a new 9mm Glock model, the G46, which features a rotating, locking barrel. This file is posted to an AR15.com user's Google drive, so I'm not sure how long it will be available. The G46 is on page 7 of this PDF file:

Overall, the pistol appears to be Gen 5-ish, but with a longer beaver tail, and obviously the new locking barrel design. Seems like potentially the biggest Glock design change since the company got started.

I have no personal insight into this type of barrel, so I'm interested to hear what you all think of this new design.

Original Post

Mark, someone referenced the Beretta PX4's rotating barrel on the other forum also, so I'm guessing you're correct. Another post mentioned that the G46 is being evaluated by Germany's GSG9, but I'm not sure if that was lifted out of the article or just RUMINT. I'll try to look over the article and translate some of it when I get to my home computer. Hopefully a German-speaking member will beat me to it...

No, Mojo you are correct.  The PX4 Storm (and the 8000 before it) has a similar rotating lugged barrel.   Pretty sure the 1912 Steyr is this way as well.  From what little I understand of the article, the Glock 46 exists to be a viable candidate for German Police pistol trials/selection.  

I'm curious to see how this one plays out in the long run

M1907 Roth Steyr 1907.  Note that the way the striker works so far as being only partially cocked is very much like the other Glocks...it's almost like Glock is going back to the very first Austrian pistol with the return of the rotating barrel.  I owned a cutaway M1907 - a very interesting early automatic pistol.

So on the fly, the file 3_ACR SCOUT linked to is out of the newest (October 2017) issue of Deutsches Waffen Journal. I haven´t read if fully now, so nothing on the technical details, but on their homepage is a short text about it.   highlighted by me

Brand new pistol Glock 46

For decades, Glock has been using it´s tried-and-tested pistol models, only altering details in the various generations, such as in the Glock 17 or Glock 19. The engineers in Deutsch-Wagram now developed the Glock 46 with a new locking system.

While almost the entire professional world still think of the 5th generation of Glock 17 and Glock 19 as the great Glock novelty of the year 2017, we have seen the real novelty, the Glock 46, dismantled, assembled and shot with it.

 

The fact that the manufacturer from Deutsch-Wagram is launching this model on the market does not mean that he is starting from his previous models to say goodbye. For this, these pistols are much too good and much too well introduced in soon 100 countries. These numerous well-known models now receive a „competitor“ from their own company, which shall ensure that additional markets can be developed, for example in Germany.

 A clear statement by Glock CEO Dr. Stephan Dörler: "With our new G 46 with 9 mm × 19 revolving barrel locked, we do not carry out a paradigm shift and introduce the replacement of our previous models. The new G 46 is intended for authorities and supplements the consistently continued line of our basic pistols like Glock 17. "

 Glock has designed the G 46 to be able to participate in calls for tenders by the German police forces. For this, the first hurdle, the TR, the technical guideline for pistols in the caliber of 9 mm × 19 must be overcome. The second hurdle is the rules: ER, testing guidelines for the technical guideline. The author of both works is the Polizeitechnische Institut (PTI) of the German College of Police (DHPol) in Münster. The TR-ER test procedure is then carried out at the  Beschussamt Ulm.

 How the sparkling new Glock pistol, designed by Generalmajor a.D., Dipl.-Ing. Friedrich Dechant, a Koryphae of gun building, is built, locked and works, read in detail in DWJ 10/2017. The issue will be published on 20 September.

 +++++++++++++

Dipl.-Ing. Friedrich Dechant  by the way played a leading role "war die treibende Kraft... (was the driving force...)" in adopting the Glock pistol in 1982 in the Austrian army as standard pistol. He retired off the Army as a General Major  and was at the end of his career head of the "Amt für Wehrtechnik" (testing and procurement authority). 

In Germany for the police only the GSG9 uses Glock pistols, because they are "special enough" to give a fuck about the mentioned TR (Technische Richtlinie)

In TR-Rand-Nummer 2.2 it is said, that a de-cocking for manipulating the pistol (and that includes to disassemble the pistol!) has to be done without pulling the trigger, for reasons of safety.  And we all know to disassemble a Glock, do we?

So...  no Glocks for German Cops - till now.

There are calls for tenders for new pistols by the Police of Berlin and Bavaria, other federal states in Germany are to follow (most Hamburg police officers are still issued SIG Sauer 220  pistol in 9x19 with single stack 9 shot magazines and carry only 1 or maximal 2 spare magazines on patrol)

---------------

So I´ll go voting now !

Is a rotating barrel more accurate than the Browning tilt design? I gotta believe feeding alternatives to ball ammo may be an issue. 

These days, with the browning lock mature as hell, I am not sure there's any difference in things like accuracy.

It could be made with a lower boreline, which is always better, and appears to be.  

Only other distinct advantage I recall for rotating barrels is that primary extraction involves twisting so you get a more effective breakaway force, much as it does with a rotating bolt. 

ETA: Is it 100g lighter than a G17-5 or am I not getting apples-to-apples weight comparison?

Some quick technical details from the article:

Page 70 in the DWJ magazine = Page 7 of the linked file

 The G46 will be decocked by twisting the back plate (p. 70 figure 1 no. 1)

 Trigger and triple safety feature stay the same as „standard Glocks“

 Metal surfaces are nonglare  DLC (diamond like carbon) coated to make them extra smooth.

 Barrel and chamber are hammer forged / no feeding ramp so fully encloses cartridge if barrel is in battery and shot breaks (= no blown out magazines and split up magazine housing / grip if case ruptures during shot???  )

 Grip end is „generously funneled” for easy magazine change.

 On page 9 is a picture of a 5 shot test group with RUAG Action 4 ammunition (most used German police standard ammo) approx. 40 by 25 mm at 25m

 (some info on the ammo here   ht tps://www.ruag.com/sites/default/files/media_document/2017-01/9x19_Deformation_Ammunition_en_low.pdf       and here      h ttp://dse.lu/ruag_ammo.pdf )

 Less climbing of muzzle due to bore axis deeper (nearer to grip) and only back movement of barrel, fully delocked after 2,8mm back travel. Lower felt recoil...

 G46 shall fit „normal” (existing that is?) Glock holsters.

So on the way to observe the ballot count.....

 

 

Rotating a striker assembly again reminds me of P7. I know that removed it but still. Wish G talked about their design process a bit more.

Rotating should seem to be able to be intrinsically safe for decocking. I do worry (a bit) about the ergonomics of twisting a little thing on the back of the slide. Safely. In the dark. After a UOF incident when adrenaline is up. Etc.

Why would you be decocking the gun (only required for disassembly as far as I understand) under that scenario?  Wouldnt you just reholster it like any other, standard Glock?

The decocking feature is only for disassembly, not like decocking a DA/SA pistol.  

Ah... That helps a lot. I thought (since it's German and I only get so much of this) it was a "we need the ability to decock" generally requirement. Presumably this just eliminates all those worried about pulling the trigger to strip, though it seemed like a bonus safety check step to me.
