I like Sig's night sight combination they offer on a few of their models like the Equinox and SCT..it's a TFO front sight combined with a sig 2-dot night sight in the rear. I was wondering if it's possible to use this combination with another brand of gun like a Glock,XD, etc with success. Or is the height of the front sight incompatible w/ the stock specs on other guns? Would it cause you to shoot high or low?
