The CBJ-MS is a submachine gun designed by Swedish arms developed Carl Bertil Johansson, perhaps better known for his remarkable armor-piercing 6.5x25mm CBJ cartridge. He developed the gun at about the same time as the cartridge, on his own time while working at the Carl Gustafs factory in Eskilstuna. While it bears a lot of visual similarities to the Uzi, and it is an open-bolt simple blowback action, it has a unique and clever fire control system – and several other creative features as well.

It looks like you blow in the back to make it whistle.
I know companies have just so much money and capacity and can’t do all projects. But I would think having a nice submachine gun, which they already have in house, to use as a platform for a new cartridge would help promote the cartridge.
I can’t quantify why, but for some damn reason? I hate this weapon a lot less than all the other “PDW” things out there.
Maybe it’s the common-sense caliber choice and the sturdy construction, I dunno. I just like it, from what I can see of it from here.
PDW’s are not full on battle firearms. They might push the enemy away, but they won’t win the battle. They would be good for the guards at a facility, when anyone trying to break in does not have a full on assault rifle
I do get your comment about being a better design than what are being pushed as a PWD. It would be more appealing in 6.5×25 to do a better job of getting you out of trouble. But even then it still won’t win the battle.
My major beef with the PDW concept is that it’s a symptom of an excruciating inability to grasp modern wartime realities.
Were you to limit PDW issue to the sort of effectively non-combatant types that the West German authorities wanted the VP-70 for, well… That’d be one thing. The idea that it’s a good idea to have the mentality that there are “combat” and “non-combat” soldiers under arms? Horrible.
If you’re in uniform, and a combatant? You have to be trained and equipped to engage and destroy the enemy, whenever and wherever he presents himself. You can’t do like the US Army did in Iraq and Afghanistan, where they wrote off every engagement with logistics troops as “irrelevant”, while having the supposed “real combat troops” out looking for the enemy that never showed itself to them.
Two-tier warfare is how you lose wars, especially the modern sort where it’s all very nebulous and quasi-organized; you could look at Iraq as having fought a ju-jitsu sort of war with the US, in that they capitulated on paper and on the battlefield, while basically going on to engage as “insurgents” in the aftermath. Unable to win on a conventional battlefield, they just shifted to what the big thinkers have termed “unconventional”.
Unfortunately, it’s all war, all the time, everywhere. There is no conventional, or unconventional; it just is.
The entire idea of a general-issue military PDW is symptomatic of “you don’t understand what’s going on, here…”
All wars are unconventional these days. There are no hard “front lines”. Anyone with a firearm needs to be able to finish the job.
I think a firearm like this would be good for police in a civil law enforcement role.
As for the military, the only situation that makes sense is in guarding a facility deep in friendly territory. The scenario I imagine is a set of guards at a gate. There would be three or more guards in the detail. In this situation there is a leader who needs both hands free to check IDs, paperwork, etc. Having something like this, with the power of 6.5×25, on a sling, for quick deployment, would be useful. The rest of the guard details would have full power “battle rifles” to be able to control any bad things that happened.
My belief, having stood several of those guard posts you’re describing, is that those are precisely the sort of targets that the enemy is going to go after, and you’d best be prepared to dominate and destroy any Spetsnatz or irregular forces that come after you.
Where I think this sort of weapon would shine is in the hands of those personnel we’ve delusionally allowed to live outside base security zones, and who’re almost certainly going to be targeted in the opening phases of a major conflict between peer-level combatants. As I’ve said innumerable times, the idiocy we’ve demonstrated by putting key bases next door to places like Las Vegas, and then allowing critical personnel to live off-base? That’s going to bite us; I can guarantee you that there are enemy agents going through social media doing targeting, and were I the one doing the planning for the next Pearl Harbor, those key and critical personnel would be the first to die via my sleeper teams that I’ve worked into place thanks to the insane policies of the open-borders idiots. I guarantee you that if you hear of a rash of “home invasion burglaries” in and around Nellis AFB, ones that seem strangely coincidental? Something is about to happen.
Putting a couple of these into the hands of those Air Force families living off-base would be one of the only PDW use-cases I’d really agree with, to be honest. Although, I’d prefer it if they were armed and trained to meet basic infantry standards, because that’s about what they’re going to be facing.
Alternatively, I’d strongly suggest moving drone operations to somewhere remote like Mountain Home AFB in Idaho, and having them all live inside the security perimeter with heavy patrols. I suppose, however, that the way the idjits have been selling farmland to the Chinese near bases, and because of the way drones have been used in the Ukraine war, that trying to provide security is a bit of a joke; those “secure” housing areas would likely be targeted for the same sort of attention that the Russians have been giving civilians in Kherson.
War has changed, and we’d best wake up to that fact. There are no “rear areas” where everything is safe; they’re going to target everything, and when they do their attacks, it’s going to be with overwhelming force wherever we don’t have anything to oppose it.
Which is why those remote guard posts better be able to handle their sh*t when it floats past.
Dressed up M-11/9 anyone?
With the caveat that this looks like it would be controllable without the silencer can on the front…
There’s something about all the details on this weapon that says “mature design”, which I don’t get from the original MAC series weapons. It’s just a feel, looking at all the elegant little details like that trigger setup. A lot of thought went into this weapon, unlike most in this space.
