Sig MPX in 300 BLK -- is this the PDW that we have been seeking?

Is this the combination that the military has sought for the PDW?
As for the Army or Marines, I don't recall seeing anything to indicate they're interested in either .300 BLK, or a PDW.

My question was whether the 300 BLK, in a short barrel, would meet the PDW standards.

Funny when you recognize the voice of the guy giving the mission brief.
That pistol model with the brace looks interesting.
MP5s have been filling this role for decades in SF, but are worn out, don't have common controls with the M4A1, and are anemic with 9mm.
This is why SOCOM needs a new PDW. Russian have had several different modern PDWs emerge over the years, including ones that fire the 9x39 Subsonic cartridge.

If the video is an example of how the new gun would be used, wouldn't it be a lot more accurate to call it a Covert Operations Weapon?Last edited by stanc; 08-27-2017, 03:37 PM.

I believe that a SIG MPX 9mm SBR with folding stock would fill the weapon needs for most of the support teams, armored crews, helo crews, etc. I carried a M16/M4 for decades and quickly picked up the "manual of arms" for my SIG MPX SBR. The "tip of the spear" warriors need battle rifles, etc. - the 9mm SBR could be a great solution for those that do not need a battle rifle as primary weapon. Anyone issued a pistol as primary weapon might be better served with a SIG MPX 9mm SBR.

Since the MP5 was typically used as an offensive weapon, "Personal Defense Weapon" seems like a somewhat erroneous classification.

Other units mainly used them for a few guys on a Team when doing SR (MP5SD3), and ADVON (MP5A3 and MP5K for some). In the ADVON role, it's a PDW all day long, not offensive. Same with SR. It's a compromise scenario option for discreetly taking out things before they get out of control. I'm talking personal experience here, not reading about some peripheral glimmer of a hint about practical application of them, with all the false assumptions that come with that.
Since the MP5s are very worn, outdated, have cumbersome aiming solution mounting issues, and bad ergonomics, it makes sense that units are asking for something more up-to-date that shares commonality with AR15 ergonomics, magazines, firepower, while still retaining the suppressed and subsonic capability of the SD3.
In the SiG video, they're showing a certain type of SR that requires a low profile, concealable system, with similar performance to an M4 within close ranges.
The KAC PDW would be another one to look at, as they have made an AR15 mag-compatible version of it that was at SHOT a few years ago even.NRA Basic, Pistol, Rifle, Shotgun, RSO

Labelling a gun either 'defensive' or 'offensive' is the tail wagging the dog. It's just a gun - How you plan to use it lends itself to one or the other label at that time. We used the MP5's all day, every day, in all sorts of missions and frankly I don't care to label it one or the other. It's just an utterly reliable, accurate and ergonomically-sound 9mm SMG.
As for the Blackout, it's not as quiet subsonic as the MP5-SD. Burns three times the powder as a 9mm for no more killing power. The heavy 30cal bullets currently used in factory ammo are match bullets designed for higher velocities. They act like monoliths on hitting flesh. Every animal I have taken with a subsonic Blackout is a through-and-through (wasted energy). But, the Blackout does permit supersonic rounds and that is a big advantage in a PDW. If SIG makes a .223 version that would be worth a look.

That is where the 300 BLK stands out is its love of shorter barrels.

A 10" barrel in 5.56 is long enough to be an effective, compact weapon. Below 10" and it arguably starts looking as effective as a 9mm SMG. Both have their roles but if you are looking for maximum effective stopping power in a compact rifle then 10-12" of 5.56 is powerful enough to 200M. Depends on your definition of compact of course and also depends on what you value more; compact or effective? More effective = less compact, More compact = less effective.Last edited by Klem; 08-28-2017, 07:27 AM.

There's a Czech 7.62x45.
300 AAC Blackout is 7.62x35. Maybe you meant that and had a double typo.
5.56 NATO does very well out of 11.5" barrels, and 10.5" with the right projectile.NRA Basic, Pistol, Rifle, Shotgun, RSO

The articles by one of the members of this group on PDWs has stated that the goal is to have a weapon that can hit out to 200m with a 5" barrel. Thus 9mm or any other current pistol round is not going to meet the standards.

JD Jones of SSK introduced it a long, long time ago as the 300x221 Fireball. That's where I first saw mention of it, before getting some trigger time with it suppressed. There are people who have been working with the cartridge for many years before the latest generation of the cartridge.NRA Basic, Pistol, Rifle, Shotgun, RSO
