I just put Trijicon HD XR sights on my 2.0 compact. Being used to aiming with the top edge of the front sight on Glocks and other guns, it shoots around 2” low @ 7 yards. If I use the front dot as the POA it shoots better vertically, but that’s a less precise sight picture. I’ll try it for a few outings, but will probably switch to Warren Carry sight (plain Black rear/ FO front).
