XS Sight for GP100

[mg2112]

Thinking about getting XS Sight Big Dot Tritium Express
for my GP100

Anyone got em installed?

I have never installed them on a GP100 before but have put them on 3 different semiautos and think thier great for getting on target fast. I have put them on two Sigs and lately a Ruger LC9.
