Wish I could answer that question for you on the 410 ejectors...some forum member more knowledgeable than me will have to. DeHaan O/U guns could be had with ejectors, but the SxS always came with extractors. Personally, I prefer extractors in my older age...it's hell sometimes picking up those hulls when the back and knees ain't what they used to be. A shooting buddy of mine ordered a custom gun from Mark some years back that is a 2 barrel set; 28 ga. & .410 bore, both sets of barrels being 32" long! Even though it was the highest grade (in engraving and #4 wood), both gauges were extractor barrels. Quite a gun, may be the only 2 barrel 28&410 SxS with 32" barrels.
