UPDATE:
Was able to take a second, much longer look at the Wingmaster and am divided.
Its condition is very good overall. Handling marks; some thinning of blue along the magazine as to be expected; two small dings in insignificant spots; forend, stock and recoil pad all excellent.
Cycled snap caps no problem; good ejection. Trigger was light compared to what I'm used to on a shotgun -- not ridiculous, but felt in the four pound range. Safety functioned properly. I was pleasantly surprised to see it had the flexitab conversion.
Dealer was courteous and affable about my checks, but wouldn't let me remove the barrel, so I ran a dry patch through it and put a light down both ends. No sign of corrosion, rust or pitting. There were long marks running the length that might have been lead or might have been scratches, it was difficult to tell. None of my shotguns have those but I keep them well cleaned.
As I was doing this the dealer said that he didn't know anything about previous ownership or use, that he'd gotten it from another dealer. Then said that at another gun show someone was checking it out and racking it too hard and broke the forend and action bars.
That surprised me.
He went on to say he'd taken it to a gunsmith who'd replaced the broken parts and put some new parts in, which I figured explained the flexitab and perhaps the trigger.
He was willing to come down a bit on price, but when I asked that if I bought it and test fired it this week, should the weapon fail to function properly would he see that it was fixed as my intention was to buy a working gun, he said no, that once it was sold he was out of it.
I can understand that position selling at gun shows where it's to strangers and many yahoos, I'm sure, but that's near to a deal breaker for me with a gun somebody already broke and in a manner that, as described, I find unusual.
I've never had seller say they had no intention of making it right if they sold me a broken gun.
So I'm conflicted.
It passed basic, reasonable checks, and it's not like 870s aren't durable (although this one apparently broke oddly) and fixable if there's an issue. Odds are if I bought it, it would work fine and that would be that.
But it has required not inconsiderable work, and I also don't like it when sellers won't stand by what they're selling, whatever the reason
And there are many 870s, new and used, out there.
Thoughts?
