https://www.guns.com/news/2019/03/04/taurus-upgrades-numerous-handgun-lines-to-new-lifetime-warrantyI've yet to meet a gun owner that thinks an endless warranty on a gun is a good thing.
Yeah, standing behind a product with a Craftsman-like warranty is noble, I guess. But so much can go wrong with a firearm over its life that is really just regular maintenance, like various springs/pins/extractors/etc. Or user modification can change a pistol's dynamic a lot. Non-OEM mags. Etc. And with a manufacturer like Taurus, you're going to send your pistol in repeatedly if it is a lemon, and the chances of it coming back actually fixed is pretty low. And lemon rate is high with them.
I think the industry would be far better served with a "no bullshit, no questions asked, 100% receipt-documented refund if you don't like this pistol for the first year of ownership" type of warranty. Guns are one of the few consumer goods that cannot be returned to the seller due to their nature. Refunds are effectively impossible, and I think this is a big driver of the 2nd-hand gun marketplace (liquidating lemons). I know I've sold a Taurus .22 revolver just to be rid of it and its problems.
A manufacturer that offered actual-price-paid refunds on pistols that they sold through distributor channels for wholesale prices before arriving at the point of sale would absolutely lose money on each unit returned. But would gain a lot of credibility for reliability by doing so. They'd also have a strong motivator to reduce customer dissatisfaction.
