I've had sight configurations with a front night sight only, but I don't like that. That's fine for horizontal alignment, but a rear sight is more necessary for vertical alignment at night in my opinion (though it may not sound intuitive at first). I'm also one of those guys who is always in search of the perfect setup, but I just bought an FNS with factory night sights and guess what? They're good enough, and I was pleasantly surprised. I built up in my head how much I wanted this or that, but you can get used to anything. The problem with Ameriglo is that they're inconsistent and have no clue about maintaining a website. They only show pictures on certain items, and they're constantly discontinuing certain models. How are they supposed to know what sells? Are people supposed to guess at what all those skus look like that they don't have pictures for? I think it's laziness. If they were working for me I'd fire them.
That said, I think their best sight configuration is a very specific one that I only see available in the S&W M&P line. It's a lime green iDot Pro with a u-shaped notch in the back with a single tritium dot and no white outline on the rear sight (so it's subdued during the day). The back sight is also ledged. I love that sight, but I've given up on Ameriglo because they can't manage their marketing department well enough to know what they should be making.
