This makes pushing forward and pulling back motions easier and more natural feeling than ever. Also, like Porsche knobs, the base holding the GS3’s hemispheres is home to a small groove that your fingers naturally gravitate towards. It just feels right in the hand and was meant to be there.\nRaw Machined Finish with included Chrome Crest Coin.\n","images":["https://cdn.shopify.com/s/files/1/0024/4898/2060/files/MachinedFinish2_square_7b2ffa08-7330-4097-ad8c-861d7ab85ddf.jpg?v=1708380416","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/MachinedFinish1_square_409dfa2b-7c15-40f1-847b-5d2ee4df8efe.jpg?v=1708380416","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/both2_square_3ca2918c-f47a-4dcb-9475-51b520a0eeb9.jpg?v=1701975793","https://cdn.shopify.com/s/files/1/0024/4898/2060/files/both_square_5beb6cfa-6d59-4cb6-bfce-87f333f88abc.jpg?v=1701975793"],"price":224.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T14:56:22.844Z"},"share_url":"https://firestarter.network/l/lst_J0Czpo2h","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
