Martimus, can you post a photo or two of the HD's on your Shield? I definitely want tritium sights on my Shield 40 but want some confirmation that what I buy will work perfectly. Also, if you have the part number from Trijicon that would really help. I have Trijicon's on my G23 gen4 and love them - especially compared to the stock white 3 dot. (I also have"old eyes" and need every bit of help I can get!).
Thanks!
