Want a cheap 410 break-open single shot and I've found a couple that are both NIB. A Hatfield which is Turkey made and a Rossi that comes from Brazil.
The Hatfield's barrel is around 26", but I do want to cut down to around 19" for my purpose. Walnut furniture, ventilated rib, trigger guard slide rearward break-open design(don't know how well this will hold up over time), receiver made of 7075 alloy, and a few videos of modifications some people do to them and of course the cost of just over $100.
Also, seems to have a few components available from company like firing pins/springs/stocks/barrels(no 18" lengths though) for replacement parts.
This while being cheaper, is designed and input from same man, Tom Hatfield who made the, what are now quite expensive Hatfields from years past, but is now made by Turkey manufacture Huglu, that many of today's guns come from.
The Rossi is not the Tuffy, but is the 18" barreled youth model, but with adult length plastic stock, as I compared length with a full size model of 410ga. No ventilated rib, but what I think is a better break-open action using a push down metal tab design.
Price higher at $140 from local shop. Doesn't seems to have much available for parts replacement that I can find, and not much for videos for mods, but more of reviews.
