Why? All his custom-built M21's had the single selective triggers-- With that option, you can choose whether to shoot the tighter choked barrel first, or secondly- in your "chain-of-fire" scenarios.

I use the M21 my late father left me in 1980- for upland birds (preserve fezzants) over pointing "dawgs""- so I always use the open choked barrel first, reserving the second more choked barrel for the second shot- if needed. Old habits die hard!!
