Wow, that's a lot of info! Exactly what I'm looking for. First the model 19 IS blued. The front sight post is a red ramp. The grip is a square butt frame. I do not see any pins in the front sight like the one I can see in the pic of your 627. I like the sights in the picture because of the low profile they present. I checked to see what it would cost to have tritium viles installed in the extreme duty fixed sights and don't think I have that to spend right now. But I will most likely pick a set of those sights up and install them myself in the not so distant future. Probably will need to stone the front sight down a bit from the look of it. I will definitely be investing in two things this week. Hogue wooden grips in Coco Bolo (because those have to be the most gorgeous grips I've ever seen) and a working digital camera.
