What other accessories might I need?

I recently just got my first two suppressors. A Rugged Obsidian 9 and an Otter Creek Polonium K. I plan to use the obsidian 9 on my ruger pcc. Rugged has the deal for a 250 dollar e-gift card so I’m getting the 9mm 3lug adaptor and the 9mm 3 lug mount. I have about 40 left on the gift card, and am happy to spend some extra cash. But what other accessors should I get from the Rugged shop?
