I've had a 12 ga. since 1985, a 20 ga. since the mid '90s, both SSTs, both Sporters. The 20 is marked something like "ASSEMBLED IN KOREA FROM JAPANESE COMPONENTS". The 20 stock is lighter colored than the forend and slab sawn, not a good looking stock. The 12 developed an "optional" extractor quirk -- spent shells are merely elevated unless the barrels are pushed open very firmly to the max, then will eject. I had Briley's install choke tubes a long time ago, and asked them to fix the ejectors, but it was no easy fix and I decided not to put a lot of money into repair -- can't remember the details.
