Talo is a distributor, so Palmetto got them from Talo instead of directly from Glock. Usually ones from Talo have fiber optic or night sights, everything else is standard Glock. I cannot tell for certain that the one on palmetto has any special sights on it. It may have standard sights on it. But for $399 any upgraded sights would just be a bonus imo.
The Q&A section on there says it has a black rear U notch sight and an orange front night sight. The description doesn’t say that so I would probably call and confirm that before having that expectation.
