A little help from the cognoscenti please.
Not being a Glock guy, I only pay a tiny bit of attention to Glock stuff. Now that I find myself with a 19x, I would like to change to some fiber optic sights. I went to Ameriglo's page and they made it a point to have Gen5 separate, and there no options available. I tried a search of P-F, but I think the search terms are too broad and I did not really find an answer.
So my question is this: are gen5 sights different and that any others for prior models are not applicable?
