XS sights "express" pistol sights

[Air.177]

Anyone else on here have these sights? I just had a chance to shoot a glock 17 with the Big dot 24/7s, and While I still prefer three dots, I think I could get used to the express sights pretty quickly. The idea is sound, as African hunting rifles have had shallow "V" express sights for years and years. It is just so different from the sights that I am used to that it will take a lot of getting used to. Any thoughts?
