Has anyone used one yet, how do they feed, have they added the side clips like westley richards do?

Is this available as an option through CZ? I don't see it on their website as a factory option, custom shop maybe?

It's a bit confusing, they do two versions of the safari classics the magnum express (longer action) and the express which accommodates the .425 westley richard CZ express

I see. Thank you for explaining. I was looking under the 550 magnum variants.
