I had the Simmons 4x32 pro hunter pistol scope and the eye relief was closer to 18-20". I guess the specs may have changed though.
The only place I've seen selling pistol scopes in the UK for quite some time is Uttings http://http://www.uttings.com/?categ...tolscopes.html.
If you fancy an alternative chances are it'll mean importing, special order or buying second hand.
