Yes, and the DM determines their AC, HP, and resistances and immunities. It's non-functional for a "laboratory" simulation. No DM in their right mind is going to have held objects use the "suggested" values for tiny objects in the DMG table.
But let's set that aside.
I pull out another hand-crossbow from my bag with my object interaction, and make five attacks using action surge and my bonus action from crossbow expert. Using SS I have -5/+10, giving me 25% to hit, doing 16.5 damage per hit. Spamming precision attack adds 4.5 to each attack roll that misses. Three attacks hit, doing 49.5 damage. You're dead.
