So you want to make a suppressor for 9mm that works for 300 blkout?

sort of like a Liberty Mystic X? which is 8 inches long and 1 3/8 diam.

Look into SD tactical or Apogee tubes. Decent info there

Volume, gives gases a place to go and hence quieter can - up to a point
Smaller - means you have to work the gases harder so you can use a coolant for a "wet" can.
The can is preloaded with Ablative (sacrificial coolant) which allows it to be quiet until the
ablative is used up.
Vs. "dry" can which needs more volume as no coolant required to get down to the same db
if you add ablative it can further reduce the volume but most are hearing safe without it.
most are between 7-9 inches and 1 to 1.375 diameter
AAC TiRant Length: 7.9". Diameter: 1.38"
AAC Eco-9 Dimensions. 8.4"; 1.25"
Mystic X Length: 8” Diameter: 1.375”
Gemtech Tundra Length: 7.2" Diameter: 1.25"
Silencerco Osprey 9 Length:7.06” DiAMETER:1.301.75” box shaped
Silencerco Octane 9 Length:7.50” DiAMETER: 1.37”

I have a "wet" (you have to put ablative in it (water, Gel, Grease) held in by a wipe and it's only good for about a mag's worth before you have to recharge it.
It's the smallest package, Length= 4", Diameter= .98", Weight= 3.1 ounces - Material= 100% Titanium

Another Wet can is AWC ABRAXAS™ LOA Length: 5.7 in Diameter: 0.98 in

compared to a "dry" can which is larger but less fuss to use.

the other thing is weight - if you have a pistol that has barrel movement (browning tilt barrel, Walther/Beretta barrel lock on sliding barrel, etc) you need to have either a very light can or one that has an Inertial Decoupler aka Neilson Device which is a part that threads onto the barrel that's spring loaded against the suppressor so as to allow the barrel movement while the weight of the can is decoupled from the mass of the barrel.


Apogee tube is sized for freeze plug DIY better product for that is Diversified Machine
I assume that SDTA is similar product but don't know about their construction.
