I recently joined the dark side, myself.
I just sold a gen4 17, turned around and bought a 19 because I was tired of waiting on the gen4 19's. I guess I'll end up selling this one once the Gen4's come out.
I didn't get the trijicons this time. I decided I'd rather have some heinie straight eight sights. That's right, I omitted factory night sights so I could buy some heinies. Don't tell my household-5.5. (She stays here often and eats my food, just doesn't live here.)
