Yes, you can safely carry almost all modern DA/SA semi auto's with a loaded round in the chamber and the hammer down so long as your holster covers the trigger.

Glock doesn't have a safety so that's a mute point. The only real design that is made specifically are the SA only guns like the 1911 to be carried cocked and locked with the safety on, of course.

If you do feel safer to have the chamber unloaded but carry the mag fully loaded that's fine. You just have to rack the slide when the need arises. Yes, for the die hards out there it's a waste of time but if this makes you feel more comfortable and you carry more then so be it.

Remember never let your guard down with a gun - just that one time is all it takes. Never say "I'm the only one in this room qualified to handle this gun.... Boom!" So, that's what happened to the DEA agent when he was teaching a classroom on gun safety.
