I use the Glock because it works the way it does. A good holster is paramount, and keeping your finger off the trigger until ready to shoot helps too. If you use a Glock the way it is supposed to be used, the three safeties included work just fine. Never had an AD and I've been using and carrying them since the 90's also.
My wife carries one too, hers is in a purse with a less secure holster, it still covers the trigger well, but I felt better about putting a NY2 in there. Mine has a polished 5.5, so it really pulls at about 4.5. My range pistols have a 2.5 pull, and if I had to, I'd have no problem carrying them either using a Serpa lvl.2 holster.
If not having a manual safety is an issue, get another pistol. I can see needing one on a 1911, but not so much on a striker fired pistol designed like the Glock. FN may be more your speed. No problem with you or your mindset, you just may be better served by a pistol like that instead of the Glock. Your mind may be at ease, and that is worth a lot.
