Sionics M11-9 Suppressor - SilencerTalk

This image is from your link. Looks like several handfuls of car bulkhead grommets, ???from the first stage of the suppressor??? Weird.

Yes, those Sionics suppressors used hollow rivets as an absorbsion system. I don't know that it was any better than anything else on the market. Pistol calibres with their slow heavy compact bullets perform best through wipes. Pre-perforated wipes work best, and neoprene is slightly superior to rubber or leather, but all of them still degrade very quickly (10-15 rounds max). That is perfectly acceptable for covert military use.

@gundoc, have you any advice for someone wanting to give this a try? Iv got a Schultz and Larsen Thunderdome for my .45
Where do you think the wipe would be best fitted? Would a wet wipe (oil) be worth a shot?
Cheers.

Oiled leather works quite well. The wipe needs to be supported on either side by washers, the rear washer needs a hole at least 1mm over bore size, and the front washer needs to be about 8mm over bore size to give the wipe room to open cleanly (assuming 3-4 mm thick wipe). Put a cross slit in the wipe at least 1.5 times bore size, and a 3mm hole punched in the centre. Two wipes work best, one at the front of the suppressor and another inside closer to the muzzle (but still at least 30mm away to avoid too much burning).

Cheers. I can see one advantage even if not max suppression: easy to pour out and pour in replacements! Imagine it would be fun trying different fillers without spending hours cutting them to shape.

the article I read on it just after I found the link this morning said they also helped to absorb heat. On a mac 10 it would be a good idea. single shot not so much.
It was also commented on that newer designs were efficient enough not to need them.
