Technical question about the new Vickers 19: It is listed as having the usual Vickers rear sight, but then also an Ameriglo i-dot pro front. I have looked on Ameriglo's website, and I don't see a sight that would work with the Vickers rear, which requires a .230" tall, .125" wide front. Any idea if this is some new Ameriglo front for Glocks that is not yet available? Is it available but not a catalog item? I would like to think they didn't just slap a .140"W .240"H front on it and call it good.
