I have both Heine and Sevigny sights on my Glocks. The front sight height on either set is .210. So the sights can be interchanged. The combo I like best for carry is the Sevigny plain black rear and a Heine front with tritium. I dont care for the white outlined tritium insert on the Sevigny carry sight. I also like that the Heine is serrated. On my Game Gun G17 I used to be a hard core Heine guy until trying the Sevigny comp sight set. These sights are really fast. Now I just gotta catch up.
