Best cup stack for a 7.5 inch B tube?

Hey guys.

I really don't know much about cans.
But I'm building a can for a 9mm P226 and it will hopefully work on my Sub-2000 9mm carbine as well.

I already got the dies, and the booster. Awaiting my order for SDTA and form 1.

What's the best way to stack my cups?

I was going to stack them all without any spacers And the smallest possible blast chamber. And if I get any blow back, I can always drill some weeping holes in the first few baffles.

What do you think? This makes sense to you?

you need to have a good size blast chamber to catch the first pressure coming out. then stack away the rest. the larger the blastchamber the better the reduction.plus i like wet suppressors. drops level by 10-20 decibels.

I would go with a DTube by the time you drill for a 9mm there will not be much baffle left and when you say cups do you mean formed freeze plugs or cones you should look at the form one suppressor forum those guys are doing some cool stuff with pistol caliber cans
