Or, lacking that knowledge or the motivation, one can just manually cycle the slide. And again, not all subsonic ammo is quiet. The missing crack is just one aspect of the report. If your goal is to pick the ammo that has the quietest report, is manually cycling the slide really a "failure" or a "malfunction?" I posit that it isn't necessarily.

I started my saga in trying to find quiet and reliable subsonic 9mm ammo back in October. In that thread, I referenced some Federal AE9FP I bought a case of that is indeed subsonic, but without putting it on a chrono, all I can tell you for sure is that it's noticeably louder than all the other 147gr 9mm I've tried. That kicked off a search to find the quietest, and what I can tell you is that in the same setup with the same gun and the same suppressor, my results have varied more than I thought they would. What I've done so far has been limited by time and money, but could realistically be accomplished in a single range trip with a dozen different boxes of ammo. It's entirely in the realm of possibility. Guys do this all the time with carry ammo, but selecting for reliability and accuracy. If you brought it down to one metric, and that being which is quietest (and not caring if they even go bang because you're going to manually cycle the gun anyway), it's even less involved than the selection of carry ammo.

I disagree with him about the shooter being surprised the gun didn't cycle. It doesn't look like that to me at all. Based on that, he draws some conclusions I don't agree with. See above.

Everyone wants to jump to the conclusion that the guy doesn't know what he's doing because the gun didn't cycle, that it was a malfunction. I'm not saying he's Jason Bourne, but I am saying there's another entirely reasonable possibility here: He selected ammo based on what was quietest, and that quietest ammo was stuff that wasn't stout enough to cycle his setup. It's not giving him any more credit than it takes to buy a half dozen or a dozen different boxes of ammo and go out in the countryside by himself and spend an hour trying them out. This shit isn't rocket science. He could have known it wouldn't, and I think he did based on the body language and not hesitating to manually cycle the gun.

Yeah, I agree with you. He didn't seem surprised that it didn't cycle.

He was clearly trying to make a quiet hit but he made mistakes if he wanted to get away with it. The big one, I think is going to Starbucks and leaving DNA evidence behind. I think he will be identified and found.

My experience with centerfire pistol ammunition is there is nothing out there that won't make an audible sound when fired. There is simply too much gas to be contained by the suppressor, hence there is sound when the gun is fire. It is possible to make a 22lr almost completely silent, but the mechanical sounds of the pistol cycling will still be audible.

My friends and I are actively involved in this exact process right now. Saturday, we're getting together to shoot out in the desert, and one of the agenda items is pooling a variety of subsonic 9mm to see what all runs the quietest in our suppressed PCC's and pistols. For those of you who haven't gone through this kind of experiment, I'll go ahead and tell all of you that subsonic doesn't always mean quiet - and some of it is surprisingly loud, even without the crack.

You mean this Glock 47?

I know it was a silencer and not a noise suppressor because (wait for it) NO gun shots can be heard on any of the videos!!



oh and for those of you not fully up to speed with modern weapons, the media has found out about the Glock-47.

It is a pistol variant of the AK-47 made by Glock. Not too many exist.

UnitedHealthcare CEO Brian Thompson’s suspected killer arrived in NYC last month on bus that left from Atlanta: sources

https://nypost.com/2024/12/05/...rom-atlanta-sources/

The suspected killer who gunned down UnitedHealthcare CEO Brian Thompson came to New York City on an interstate Greyhound bus last month, police sources told The Post.

The suspect arrived at the Port Authority bus terminal in Manhattan back on Nov. 24 after the vehicle set off from Atlanta, Georgia, according to the sources.

It wasn’t immediately clear, though, where the cold-blooded gunman jumped on.

After reaching the Big Apple, he checked into the HI New York City Hostel on the Upper West Side before going to stake out the Hilton Hotel in Midtown, where he ended up killing Thompson early Wednesday.

He appeared to have checked out of the youth hostel for one night before returning in an Uber a day later — on Nov. 30 — to rebook a room with a fake New Jersey ID, per sources.

Meanwhile, cops released chilling surveillance images earlier Thursday that showed the killer’s unmasked face for the first time as he flashed a smile in the lobby of the hostel.

Sources say the gunman only pulled down his mask because he was “flirting” with the receptionist — and she asked to see his face.

Cops and FBI agents subsequently scoured the hostel, but a search of his room — which he shared with two others — had yielded nothing of note as of Thursday afternoon, according to sources.

The developments come as cops slowly piece together the gunman’s whereabouts in the days leading up to the shooting.

As the manhunt for the gunman continued, sources said cops had since recovered the burner phone he ditched as he fled the crime scene and disappeared into Central Park just minutes after killing the executive.

The suspect was seen making a call on the phone as he made his way to the hotel on Sixth Avenue, police said.

Officials have also found one of the water bottles that he purchased at a Starbucks at West 56th Street and Sixth Avenue — just a few minutes from the hotel.

Of course, but mind that I never said anything about no audible sound, I just said quietest and elaborated on that further in a subsequent post. The quietest 9mm I’ve shot in my setup so far sounds about like a paintball gun. In a cityscape, I could see it being mistaken for a number of other things, and on a street with lots of hard surfaces to echo off of, harder to pinpoint where it was coming from. Paired with not immediately running away, I’d say if his goal was to keep a lower visible and noise signature at the site of the shooting, he accomplished that. That’s a reasonable goal. Total silence isn’t, and I’m not saying it is.

The way I describe the sound is that it’s not what most people would associate with a firearm. My 45 acp suppressors sound like a pneumatic framing nailer. Unless you’ve experienced it, you’d think there home improvement happening nearby.

Would imagine they have that call number and are working on the recipient to determine more information...

I was just using your post to springboard off. I completely agree with everything you wrote.

Interesting. I was contemplating suppressing my bedside gun (P220 45 ACP) to protect my hearing in a worst case scenario. Currently I have Howard Leight Pro muffs next to it.

But I did some online research and the website said a suppressed 45 is still about 130-134 dB. That's still pretty loud and indoors, I'd still need hearing protection.

If you fired your suppressed 45 in a confined space with ceramic floors, sheetrock walls and sheetrock ceiling, would it hurt your hearing?

If you had to fire, in a worst case scenario, that would be the least of your worries.

It appears to have been made to appear as if it were taken from a fixed-position security camera yet after the shooter starts to leave the scene, the camera pans to follow him, then stops abruptly as the cameraman realizes he shouldn't be doing that if he wants to maintain the illusion.

Or am I so out of the loop to not know that security cams will follow movement?

Well, they didn't want to pan over and show the shooter on the grassy knoll.

I’ve done exactly that. It’s loud. Carpet and furniture change everything though. They tend to absorb the sound. But the room you describe would be loud. It wasn’t deafening nor did my ears ring nor sound distorted after. But I would probably still use the electronic hearing pro if possible.

Is new comish-Tisch releasing all this info so it looks like they're doing something, or is the intel leaking from NYPD like a sieve?

Reporting is that they think he got on a bus back to Atlanta about an hour after the shooting.

Trying to catch up on this event and the thread. At this point, considering he has apparently escaped NYC, there's the possibility it went off as planned.

The video proposes he ejected every other round, the ones with writing on them. Who knows, but maybe the firearm functioned perfectly?

So I haven’t seen the video. Everything I have seen is stopped before the first shot. So I don’t see the racking of the slide. Feel free to link me, or say where the un youtubed video is.

Is it possible that the shooter didn’t completely understand how a semi-auto operates? Maybe the ejected live rounds were by accident? Maybe some stooge that did this, and thought he had to cycle the slide manually each time?
