Avoid Spanish single triggers, ESPECIALLY in 10ga--doubling in a 10 Mag. cam't be pretty..... Only ones I've every fired were Zabala Hermanos, which are usually pretty rough guns that function fine. A Beretta Model 410 in 10ga, if you can find one, is a nicer gun. A well-preserved NID 10 "New Mag" is kinda the "Holy Grail" of sky-scrapers. (Personally I think the "Old Mag" (2 7/8") is plenty for 95 percent of waterfowling.)
