"subsonic projectiles" eh? I can guarandamtee you, a 300aac blackout, 8.5" barrel, suppressed running 220 gr. SUBSONIC AMMO will blow through a 24" diameter live tree where a 223 with a 20" barrel doesn't even come close.
And for handgun ammo, you have to specifically buy subsonic to get it, and it's more expensive usually since it's meant for suppressed fire (obviously)
i think 9mm ammunition is usually in the 1200 fps and 115 grain, and to be subsonic you have to be under 1000 +/- fps using 147 grain or higher bullets

There are a nontrivial number of auto door amateur ballistics tests out there.
Don’t count on some sheet metal as cover even while some dingo is measuring his block of clear gel.
