Form 1 design for 9mm PCC

Hey Everyone,
Newb here looking at designing a can for my AR9 pistol build. Was thinking of a 1.5 x 7 or 8" SDTA Ti Tube filled with radial SS cups. Direct thread 1/2 x 28 mount. A 1" spacer after reading on here to keep the blast chamber small for pistol calibers. Does it make a difference if I make the spacing between the first baffle/cone more than those subsequent? Should I also make the spacing on the final baffle to endcap(distal) larger? I want to run mainly subsonics through this can and I am concerned of building it too large, too many baffles for the subsonic ammo to clear and or the gun to cycle. My AR9 has a 8.3" barrel.
Thanks in advance
