Ruger Police Carbine "out of battery" device

[halfmoonclip]

All our discussions of blowback 9s got me wondering about the Ruger Police Carbine.
We're talking the original, non-takedown, that used Ruger P-series magazines.
There is a linkage, above the bolt, that keeps it from bouncing out of battery. The linkage is released, either by pulling the trigger, or tugging on the charging handle, allowing the bolt to cycle.
I guess the Ruger was made for rough service; it's stout enough that it would give a mean butt stroke, something I wouldn't try with, say, a Scorpion or MPX.
But I'm not aware of any other blowback, closed bolt carbine using such a device. Does the current, PC 9 use one?
Any insight from the group?

The Beretta CX4 has a mechanism for the same reason. So if the gun is dropped on the butt, the blowback bolt won't cycle. Which could cause a cartridge to feed from the magazine into the chamber. Could be a problem for police or military that carry the gun with a loaded magazine, but are required to have an empty chamber.

See item 59, inertia bolt stop. It's spring loaded to stay out of the bolt (item 17) when in normal use. But if the gun is dropped on the butt, its hook moves into a cut out in the bottom of the bolt to keep it from chambering a cartridge.

Thanks, chicharrones. Had a Storm carbine, but was unaware of this.

The new style PC9 doesn't have it. More like a upscaled 10/22 or Marlin.

Been reflecting on this, and the more time passes, the more I think the 'buttstroke' thing has as much do do with the bolt check device as anything.
The old Police Carbines have a military feel to them; you could really knock somebody on their ass with one.

That device could be modified easy enough to hold bolt closed when fired if applied. That would no doubt make it MUCH quieter than a semi 9mm carbine when a suppressor is added, just saying

Really liked the original PC9 and PC4; had a couple of the latter. Had they taken Glock magazines, I'd still have them. Heavy duty is right.

The current one is my second; this one has an aperture sight (huge improvement), and the first was during Bill Ruger's 'guns for honest citizens' phase, meaning there were only 10 round OEMs available. I had aftermarket, full capacity, magazines, which worked well enough, but it simply bugged me.
That first one was my first 9mm carbine, and still really like the concept.
The current one came with a pile of aftermarkets as well, and I acquired a couple three P-series 15 rounders.
Gunmakers addressing the magazine issue, as the current Ruger does, is really an inspired idea.
Gordon, that is a clever idea. It would require threading the barrel as well, and there isn't much room in front of the front sight.
I've been avoiding the suppressor rabbit hole...
