Hi Robert, if you are talking about this (non expert) model budsgunshop.com/product_info.php/products_id/713096817/walther+hammerli+x-esse+sf , it is also an 'expert' model. The difference is the color, this one is black (Bud's is not using correct picture) Correct picture here >>> https://shop2.gzanders.com/firearms/walther-hammerli-x-esse-sf-expert-22lr-6-as-10-shot-g2870258us.html
Stay safe & have a great day!

Hi Robert and welcome. The Expert SF pistol is a new variant among the X-ESSE family of firearms with huge upgrades such as the walnut match grip. This sport gun is reminiscent of the legendary Hammerli 208S in precision, design, and workmanship. All surfaces have been finished with the proven Stinox coating process. Cheers and stay safe!
