HK4 .380 Barrel

I recently inherited an HK4 from my dad. Came with three of the four barrels. Missing the .380 barrel with spring. Wondering if anybody had any ideas where I might be able to purchase this missing barrel. Thank you.

Make sure you address the buffer before trying to shoot .380 out of it.
