I take it you're comfortable with the molded holster touching only where the trigger guard meets the frame. Doe it feel secure or does it move in the holster?
Yes. I carry guns to use them, so I expect them to get a bit of wear. They move in the holster a little bit when running or jogging, but they are relatively secure. I hit an eight inch high cable one time while running, tucked and rolled and ended up skidding a little on the holster that was in my back. Skinned up the holster a bit, did not hurt the Glock noticibly, and everything still worked. I have carried a Glock in one for over a decade.
Eventually, the holster wore down on the trigger guard retention area, and would not hold the pistol as securely as I wanted, so I traded the old holster for a new Fobus. I carry it both concealed and openly most of the time.
No one holster can do everything, but the Fobus does a lot of things fairly well.
Most people who start carrying end up with a box of holsters that they have tried, and a couple that they use most of the time. The Fobus is one of those "most of the time" for me.
