Man, I hate to make this my first post, so take this FWIW.
I bought the Xd45c for a carry weapon, to give a rest to the Shorty 45, and because I believe having just one SD weapon is not a good idea (and any excuse to buy a new gun is good, right?).
I am not a Spring Chicken, and although I have perfect vision, my arms have gotten way too short in the last few years making it hard to focus on a front sight. I am also not any kind of expert in all this, so don't have any particular school of thought to defend.
I just got the Xd back from Goshen, and am still getting used to the sites (in fact only been to the range once with them), but I am extremely pleased. At ranges out to 10 yards (the farthest I shot with them so far) it is quite effective, and an improvement not so much in shot placement yet but in ease of use and ability to get on target. I have been running through some practice tips from Tim, who called me and worked with me for an hour after I got the gun back, and feel that the next range trip will be very telling.
This is a different concept that Ghost Rings on a rifle, and is a "Combat Sight", not a target sight, and understanding that will set your expectations correctly.
I am not going to say they are the greatest thing since sliced bread, everyone is different and I simply do not have enough time with them to say more than I have. So far, I am really liking them as they appear to do what I wanted them to do. And Tim did excellent work, with plenty of communication.
I know everyone states unequivocally that you are supposed to focus on your front site to shoot accurately, and maybe because that is hard for me to do (presbyopia) I was more willing to try the "target" focus approach. I also can appreciate the research on physiology in stress situations, because I certainly know my own limitations. Like most of you I have taken action to defend myself and my family and want to make sure I am practiced and capable of doing it, while praying I never have to.
