Sear's and a few others have imported the Zoli guns long before
Zoli started exported to the US.
If you check on Guns International, every so often a Sear's Zoli will pop-up.
They list for far more than $500. The Sear's I have has double triggers and extractor's.
You may find that the gun will pattern very tightly since the barrels are bored
on the tight side. Mine is a field gun with a narrow rib and handles well.
Good luck with your find and enjoy it.
