The scope you are looking at is designed for a rifle. You need a long eye relief scope for a pistol. budsgunshop.com/catalog/product_info.php/products_id/20085/BSA+Optics+Handgun+Scope+2x20mm+Black+Finish. This scope will require weaver 1 inch scope rings.
Other suitable options would be:
red dot budsgunshop.com/catalog/product_info.php/products_id/60675/BSA+Red+Dot+w%2F5+MOA+%26+Black+Finish
halow style

Forgot link to scope yes it will fit but it will NOT work well. For a handgun you need a scope with a long eye relief here is a good handgun scope

Hi Robert, I'd look more into a red dot sight. This will fit but you won't like it. Look at the new Nikon - budsgunshop.com/catalog/product_info.php/products_id/712016045/NIK+P-TAC+SPUR+REFLEX+SIGHT
