Model 21s are available with double triggers and the later style stock, with splinter forends, both with and without ejectors. I would expect to pay $3200-3500 without ejectors and $3500-4000 with ejectors, depending on condition. Most are found in 12 gauge. They seem to be lighter in weight than the single trigger models, probably because of the splinter forend.

I have owned one of each and still have the one with ejectors.

My "Holy Grail" of Model 21s is a 16 gauge with double triggers, straight grip, splinter forend and 28 inch barrels weighing no more than 6-3/4 pounds. I've never even seen one that meets all of those requirements and doubt one exists.
