I carry a Glock 23 and had the same concern at first. I would suggest carrying at home with the trigger set and the gun unloaded and put it through its paces. Bump it, jump with it, jump on the trampoline, whatever. It will ease your mind once you realize that nothing is going to happen as long as nothing applies pressure to the trigger. G Forces from bumps just isn't going to do it.
I also heavily researched the actual functions of the trigger safety. Glock has this one their website, not sure about any other brand.
