Pistol Bayonet is Unuseable

[Kantonine]

Describe the bug

Pistol bayonets don't add piercing damage on the handgun they're attached to, and don't display a damage change in menus

Steps to reproduce

1. Find/Spawn pistol of choice
2. Find/Spawn Pistol Bayonet
3. Attach Bayonet
4. Note lack of damage from bayonet on gun

Expected behavior

I expect pistol bayonets to be in line with the makeshift bayonet.

It's just missing a mode modifier in JSON. This seems to work:
