I guessed you would know the answer on that one Barry
I do wonder if the 430 is in effect a fixed barrel version of the D280?
Almost in a similar way to the D45 and D50T01 having the same power plant and the 50 almost being the fixed barrel version of the 45?
Possibly a little bit of history repeating with the difference of course is that we now have more efficient loading arrangements on the fixed barrel version.
Though the 430 can still be had from some outlets here it's another gun that doesn't seem to have fulfilled it's sales potential and could be another collectable gun of the future. Particularly in Stutzen guise perhaps.
