Hastings barrels are made by Verney-Carron in France. They have been fine with me quality-wise. I did a search about this firm and they have a long established reputation for sporting arm production. The blueing is beautiful (matches with the Wingmaster finish) and the accuracy been pretty good (3-5" at 100 yds) for a slug gun. To be honest, I haven't tried all of the sabot loads out there yet since they're soooo expensive. Maybe I'll get better groups with more effort. Also, the cantilever is set up for Weaver-style rings. I suggest extra-low rings and a good low power scope made for shotgun recoil (e.g. Leupold, Burris, Weaver, etc.). BTW, Hastings also has a selection of LH regular barrels (24, 26, 28, 30") for the 870. They don't have LH 1100 or 1187 barrels.
Good luck,
