Pap if you want night sights you might check with Brownells. KimberAmerica.com might even have something to fit your Glock. ElPaso Saddley or K.L. Null Holsters Ltd. are good places to look for a different holster. I am just leaving to go to the range to try out a new FN 45 that I picked up a month ago. It is a double stack and holds 15+1. The handle fits my hand pretty well and I have small hands. Now to see how it shoots.
