I metered the TPM MP5SD at the ear and MIL STD today. Need a few days to write it up.

The short 8” TPM suppressor is very quiet; I may have to buy the transitional 12” version also to see how quiet it can get.

Anyone ever compare the sound level with a regular MP5 and Octane 9 or Omega 9K can? I've got an Octane 9 with an Omega 9K on the way, but I only reload 147gr 9mm anyways. Wondering if I'll notice any sound difference between a MP5SD running 115gr or 124gr vs a suppressed MP5 running 147gr.

Quote HistoryQuoted: What's the point of using 127 in the SD and 147 in the B&T? Seems like a waste of time. As bullets out of both guns will be subsonic leaving the muzzle of the can I think it's a fair comparison. |

Quote HistoryQuoted: Can't shoot subs through the SD as the barrel is ported to slow supers down to subsonic. Shooting subsonic in the SD could damage the suppressor. As bullets out of both guns will be subsonic leaving the muzzle of the can I think it's a fair comparison. Point being, part of the MP5SD's "magic" is that ported barrel, so I would rather see him run 124gr (that the MP5 was built around) through both weapons, and see how the MP5SD stacks up against a more "modern" platform with a conventional silencer configuration. Edit: And the MP5 Operator's Manual by Jim Schatz says not to use subsonic ammo, below 140gr in the SD, so 147 in both would be fine also. |

The 147 I have is subsonic. I can run 124 through both, I just figured the supersonic crack in the APC would make it not worthwhile. No one else thought my TPM numbers were high? Quote HistoryQuoted:

Jim Schatz, who wrote the MP5 manual (at least, the PDF copy I have on hand) says subsonic in the MP5SD doesn't net much of a gain in dB reduction, so I would think a 5-shot string of 147 through both, should be about as fair of a test as you could do between the 2 platforms.

Sure you can, I have been doing it for years. The bullets are subsonic when they reach the suppressor, either way. The only issue is to have a proper locking piece to match the recoil impulse. This from G3Kurz - RIP. Quote HistoryQuoted:

I just assumed that info was on there Im surprised to see that it looks like its blocked out. Which I really hope my dealer didnt drop the ball on getting the serial numbers on the other forms that went to the ATF I remember reading the cans serial to him. I also remember that the cans info was kinda boogered up and made you look harder. It looks like they stamped one or two of the numbers twice because they didnt hit depth or something. We both looked at it surprised they left it that way. I use to have pics... but yeah, now I have a new phone
Oh wait I think I found the pics

Finally handled a SD this weekend
Man It kinda felt like a pig upfront compared to a 3 lug suppressed MP5 It seemed quite a bit quieter than other suppressed guns going off at the event, but it was honestly too hard to compare with all the gunfire going on |

Okay. Well I can build a 9mm AR, suppress it and be under 5lbs easy. As short or shorter than a MP5SD. If I do it with something like the CMMG Roller system, Im getting pretty golden now.
