The BSS single trigger is also mechanical vs inertia.
The only BSS with double triggers was the sidelock, which is a totally different gun. I have seen a couple BSS on which someone has done a DT conversion. If you're looking for a similar gun with DT, you're in luck. Miroku, which made the BSS, also made shotguns under the Charles Daly name. (And you'll also see a few marked just Miroku, or else Western Field made for Montgomery Ward.) Almost all of those Miroku doubles were DT guns. They're cheaper than the BSS (because they don't say Browning). Most are pistol grip/beavertail guns, and most have extractors rather than ejectors. They used to be real "sleepers" on the used market. Not so much any more. But they're still good guns for the money IMO, and a good choice if you're looking for something the quality of a BSS for less money and with double triggers.
