I think the bag is not too heavy. This is the strap is too narrow and ev. Cuts I could find so far nichct. However, my G15 is really easy and also as accessories does not weigh much.
I have the tabs set, but that the camera can be seen well still can not slip. An inadvertent activation is not possible with my G15. I place the power button as well as down, so I can accidentally touch him pull the camera not him.
The magnetic hangers close firmly and well with me. I see no problems coming toward me.
I do not see that the camera can be easily stolen from his pocket. I avoid the holiday crowds but also and take care accordingly if it still is at a premium. (Subway / Metro in Paris, for example)
I would buy the bag in any case again. Alone only the look and feel of the bag is unique.
