This was the conclusion I came to as well, so I completely agree, just looking for others experience to validate.
Yup, but I can only find it sold separately like that for Glocks. Based on market share alone, I understand if they only do that for Glocks, but maybe I'm just not finding the HK fronts. I'll have to call Trijicon and ask. I'm going to pick up a second VP9 soon, so I've got a 10-8 FO front on the way to try for myself.
