And where exactly in the rules are you getting this from, you can damage barriers with unarmed attacks and last time i checked those normally do stun damage.
Well... In the area for Damaging barriers...
QUOTE (SR4A Page 166)
If the weapon's modified Damage Value does not exceed the barrier's Armor rating (modified by the weapon's AP), then the weapon is simply not strong enough to pierce the barrier, and the attack automatically fails.
So... Lets see... A Standard Bullet (or SNS) does 2 DV...
Which is not enough to penetrate Average material (Barrier of 4) even with its -Half AP of the SnS.
Barrier table that is relevant...
QUOTE (SR4A Barrier Table page 166)
Average Material 4
Example: tree, furniture, plastiboard, ballistic glass
Heavy Material 6
Example: hardwood, dataterm, lightpost, chain link
Reinforced Material 8
Example: densiplast, security door, armored glass, Kevlar wallboard
Structural Material 12
Example: brick, plascrete
Heavy Structural Material 16
Example: concrete, metal beam
Armored/Reinforced Material 24
Example: reinforced concrete
Hardened Material 32+
Example: blast bunkers
Anything that that does not penetrate Barrier Rating is Harmless to that barrier. So, Most Bullets will not penetrate most barriers.
