Looking for a dedicated suppressor for my z-5p. This will be the only gun the can is used on, unless I end up with a z-5rs as well. Maximum sound suppression is the goal.

Well I have an Obsidian .45 can and love it. They have 3lug mount for both thus I would get either the .45 or 9mm of either with the three lug and put on it. I got the end cap and piston for 9mm for mine and works just as well with subs in 9mm. Even in the short configuration. Plus can be used for subs in .300BO. Haven't tried it yet since need a different adapter for my .300bo barrel. Yet for my 9mmPCC I am looking at the 3 lug and adapter for the obsidian can for it since don't have to keep checking that it is screwed all the way on. I went .45 cause I shoot different calibers than just 9mm. Will work for any handgun from 9mm-45acp. Now I just need to get a threaded barrel for my Glock 20.

3 lug mount is essential. I also have an Obsidian .45 and love it on my Z-5P in short config.

I got an Omega 9K for my PTR9. I can’t comment on how it works as I’m still waiting for its jailed release. I figure I’ve got another 8 months.
Here it is during a somewhat recent conjugal visit. The PTR now has the sliding brace. I have high hopes for it being a fun setup. Attached File |

Quoted:Maximum sound suppression is the goal. View Quote That was the goal of my first suppressor and I ended up with a beast that turned my SBRs into muskets. I used to hike and shoot on my land so having something lighter/handier made shooting more enjoyable. I think maximum sound suppression is like 3rd or 4th on my list. I think most people who buy multiple suppressors end up doing the same thing. They chase decibels. And then they buy something like the Omega 9k or a modular. The Obsidian 45 has been great on the MP5/MP5K and I wish the 9mm version was sold first. On your list, the Obsidian 9 or Wolfman would get my vote. But I don't think they are quieter than the MK9K. |

If maximum suppression is the goal the only one to get is the Phoenix. Pretty simple.

The Wolfman or Obsidian 9 will give you both quiet and ability to go short.

I have a TiRant-M on my MP5. Very happy with it.
It is quieter than many others we tested here at the shop. |

I’d go with the Wolfman. It’s user configurable and sounds good with both configurations and is built about as strong as you could want for a pistol can. Also is backed by a great company with a good history. The Rugged obsidian 9 is good as well but is more of a handgun can. Sounds good on a mp5 but is smaller in diameter and therefore isn’t as quiet.

[#16]
From my understanding the GSL is a great can but you have to run it on a full auto to notice a difference between it and the Wolfman.

Went old school years ago. Works on my MP5 and UMP 9mm along with all other 3 lug setups.

Omega 9k with Rugged 3 lug on a Zenith RS is pretty nice. Short, light, handy, but it's a k can.
Got a Wolfman in jail, which I'm guessing will match the 9k performance when short, but then go full grin quiet when long or wiped. |

Is there any good independent metering data out there on the Omega 9k on PCCs running 147s or 158s? Specifically an MP5 or even a scorpion would do

I have the Omega 9K on the exact same gun. No regrets. Dig the size and the sound suppression. Especially with subs. Guys at classes or at the range are always amazed. Can't compare it to anything else other than my Griffin Revo9 in K configuration which also sounds good.

I shot an Omega 9k and Hybrid on my friend’s MP5 today both 3-lug mounted and with .30cal front cap on the Hybrid. To spectators both were quiet but we were shooting supersonic 124s and the 9k was a little sharp to my ears as the shooter. Bigger cans usually have a nicer, lower tone. We didn’t do any mag dumps, just controlled doubles and triples. I think on longer full auto strings the bigger cans are worth the extra length. Maybe if we were shooting subs the difference would be less noticeable as well.
|

[#24]
I hope you weren't really using a .30 end cap on the Hybrid. 9mm is bigger than .30. They make a 9mm flat end cap for the Hybrid which is probably what you were using if it wasnt the .46 and you didnt have strikes.
|

[#25]
No it was the .30 flat cap from my Omega. I parked it on there to try the Hansohn ti front cap in my Omega the prior outing. Hansohn’s .30 cap is about 0.380”. The SiCo .30 flat cap is 0.405”. I’d forgotten the Hybrid didn’t have the .46 cap. It’s a good thing the Griffin 3-lug locked up tight. I had a Rugged 3-lug in the 9K.
Normally when I have a choice on 3-lug I’ll use the 45 front caps. Had I known it was going to be a subgun outing I’d have probably had things set up beforehand. Nothing makes a firing line stupid faster than full auto. |

@amphibian
So if someone were to be interested in a copy more/less of your curtis tactical can would we just contact them and say we want the amphibian special? In all seriousness it looks like all the downfalls have been corrected with your version. |

View Quote Since the new Curtis can comes completely apart, I can see the build up occuring on the baffles and will probably drop it in my ultrasonic soon. I only shoot jacketed ammo but exposed lead base bullets. |

[#30]
Thanks for the info, a few more questions.
I know you have said (ive also seen the video comparison) that the curtis version is quieter than your original mk9k, do you see any real advantage to the 8" over the shorter 5.75 if the 5.75 performs that much better to begin with? It seems that 2 or 3 baffles may not amount to much extra suppression. Thanks for any info on these differences (and for the tuning on the RDB platform.) |

View Quote Nah, I don't see any reason to go longer for this design.... ETA: The shortest barrels I suppress in regards to 9mm SMG's are my MP5K PDW and Mini UZI SMG. Both of which the custom Curtis can works just as well as my MK9K. I presume that a short 4 or 5" barrel may benefit from the longer can as that is more gas and powder to deal with than a longer barrel. I know that the trend these days seem to go for the 4 or 5" barrel but I personally prefer around the 8" length and a short can. |

[#32]
BTW, I think Curtis Tactical is doing a run in like 2 weeks as several people have been requesting what I had built. I don't know if he typically runs extras or not. So you may want to reach out to him soon to minimize the wait if you are serious.

Do you have a weight for that Curtis Tactical setup compared to the GSL? Do you think its better than an Obsidian 9 even on semi-auto? I assume the tone and back pressure would be better but ive never shot an MK9K.

I assume the tone and back pressure would be better but ive never shot an MK9K. View Quote Pictured below is one of my MK9K's which is 22.3 oz...however, this has a lot of rounds through it and how much of that weight is crud buildup who knows.... Looking at a 2016 Gemtech catalog, they list the MK9K as being 20 oz but who knows what mount they are using to determine that weight. Now my Curtis Tactical custom can is 17.5 oz. Note that I'm using the same 3 lug mount pictured with the MK9K as the Curtis to try to be consistent. Again, there is no aluminum in my custom Curtis can and the inner tube is eliminated. Being so short, I feel less of the cantilever affect since you have less weight at the end of the gun. Judging by ear, I think it is quieter than the Omega 9K....I would think so since it is bigger/heavier. Not for everyone but serviceability is very important to me. Very happy with this setup and currently getting another one of MK9K's cut down so I have another one I can dedicate for full auto UZI applications. I've never shot an Obsidian either, I'm just going off past experience of the Omega baffle design from back when it was with Joe at SWR, then Henry who then went to Silencerco and is now Rugged. I have an Octane 9 and I would presume the Obsidian could at least match that in it's long form. That said, I've always preferred the tone and backpressure of the MK9K over my Octane 9. I find the MK9K has a more pleasing deeper tone than the more modern compact cans and my new Curtis can replicates that....even for a semi application. BTW, on the run Curtis is doing, I've heard he is doing 3 lengths. 5.75" (matching what I had done), 9" and 11". Picture below comparing the new Curtis custom shorty, MK9K and then an Octane 9. Octane 9 is listed as 7.5" long while the Obsidian in long config is listed as 7.8" long and you can see even with the compact 3 lug mount, it is a bit longer than my Curtis can. Aesthetically, I also like the short fat can look over the skinny looking setup that looks like it belongs more on a pistol than a SMG. You may have seen my posts recommending the Obsidian as I think most people are looking for versatile setups. The Obsidian offers that with the modular length and still has full serviceability using materials that you don't have to baby to clean. However, I don't care about versatility as I just get more specific cans for specific applications. |

@amphibian - Once again, thank you for excellent objective information and advice regarding NFA toys! I now plan to get one or two of the 'Amphibian' cans from Curtis Tactical...bonus for me is that they are just a few miles down the road from me.
Since you are a fountain of sage advice, what recommendations do you have for a full auto 5.56 and .45ACP cans? v/r, Esox |

(I know there are some 11.5 mid's out there but that is another discussion). That said, I go with the Brevis Ultra II and also run that in full auto. Thread here: https://www.ar15.com/forums/armory/Lightest-Direct-Thread-5-56-suppressor-/20-500612/ For .45 full auto, I have an old Gemtech UMP can that I had Dater do a custom job where he swapped the UMP mount for an UZI barrel nut mount. It is OK. I don't shoot a lot of .45 full auto and don't have much to compare it to. I have a huge custom 9mm can, that I've been talking to Curtis Tactical about getting it re-cored for .45 and possibly shortened, it has an UZI barrel nut mount and is a sealed can as well so I want it re-cored with his SS threaded stack and use a Griffin Armament 3 lug mount. Really looking forward to that. Hit me up offline if you want to discuss more as I don't want to derail this thread since we are supposed to be talking about the best MP5 can. |
