Found the perfect case/bag for your Sub2000. Not expensive, not tactical and fits perfectly. Larswon Sling Bag, Lightweight Large Chest Bag Laptop Backpack Shoulder Bag for Men Women Black https://www.amazon.com/dp/B07M8NX8WJ/ref=cm_sw_r_em_api_glt_i_JGXWP698NR0X7BG8H3CD?_encoding=UTF8&psc=1
Looks like a nice option @SueNommi thanks for sharing.
Probably belongs in this thread.
I bought the Unique Case for my Sub2000. My Sub has the Mcarbo flip down mount and the Sig Sour Romeo 3 Max red dot sight (very low profile and very expensive). Once these were installed, the Unique Case no longer closed even with the Sub folded and the sight flipped down. I called Unique Cases and they NEVER returned my call. Apparently, they like my money and don’t want to have the case returned. I DO NOT recommend Unique Cases as they appear to only care about the initial sale.
Today they refunded my money. It just took a while, but they made it right. However, the case still won’t work if you install the Mcarbo flip mount with a red dot.
