Safe to carry at 4 o clock? (Sitting on the gun)

Hi I usually carry my Glock 19 anywhere from 3 to 4:30. However it kind of gives me pause because I notice when carrying at 4:00 I am often sitting on my gun. Now my holster is hard and completely covers the trigger but I can't help but feel that there is still risk of the trigger getting pulled somehow. Are my fears justified or should I not worry so much about this? Thanks. via /r/CCW https://ift.tt/3ca5x1m
