Help to make store pages fullwidth on MarketPress

I manage to create a custom sidebar for the CPT products.
But all my store/ pages that are generated have the default sidebar of my theme.
Since they are not CPT haven't been able to change the sidebar, I even would like that those pages have a full width page template without the sidebar.
My theme creates the pages with php on the next post I will post the code to see if anyone can help me make a conditional that if the page is a store page then apply the full with template

Thanks a lot
