Hey all. Hopefully I'll be picking up my 590 from my FFL tomorrow (excited ). As something to pass the time, I've been looking at accessories. Getting a Tritium sight intrigues me but I'm not sure what kind to get. My 590 is setup with the factory Mossberg ghost ring sights (not the XS style) and appears to have a replaceable/adjustable front dovetail sight. Has anyone else replaced this with a tru-glo or tritium style? I imagine you have to get the right height and style to fit.
