Springer Precision does some outstanding work and have some great products. XDs & XDMs have very difficult to remove sights. Solution: Send them to Springer Precision. Scott put Dawson sights on two of my 9mm XDMs. Nightsights with small tubes aft and a larger front. Good to go in light, not so light and dark conditions. Good company, good service.
