Just to get it out of the way it's a magazine not clip.
If YOU are uneasy about carrying a hot gun then by all means please do not. This isn't an insult its common sense.
Personally I feel a glock should be carried with a round in the chamber (by someone that feels comfortable doing so!). The trigger is fairly heavy plus you should never ever ever rely on external safeties. If you are pointing the weapon at something then it should be a target or something you don't care if it gets shot (ground, etc).
