Are they poor quality? I've never heard of them before today...
No, USFA makes excellent quality firearms, but they are rather quirky. They have a penchant for coming up with grossly over-priced, oddball stuff that would sell gazillions at one-third their price, but has no real market at the inflated prices they put on them.
Like their "1910" Colt .45 auto, which is an alleged recreation of a prototype pistol that never existed -- and isn't really a 1910 anyway, because the detailing is based on an M1911A1 frame.
They brought in a new VP of marketing a bit over a year ago, and he left within a year. Small wonder. Whoever makes the final decisions at USFA is an idiot.
