My comments were directed toward the person who asked about what condition a Glock would be considered with a round chambered. Most of today's semi-automatic pistols such as Glocks (not all, just most) can be operated as I mentioned in the various conditions. Specific manufacturers and models will vary, with 1911 style being obviously different as would SA only handguns etc. My major point being that outside of pulling the trigger, there is at least one step required to allow the gun to shoot with the exception of guns which are in Condition 0 (for models with a safety), or Condition 2 (for all non-SAO models).
I personally keep any gun I'm carrying in Condition 1 as all my carry guns have a manual safety and that is what I am most familiar/comfortable with. The decision is up to the individual on what weapon and carry method they are most familiar and/or comfortable with.
Ok, I get what you were saying now. Although with the built in safeties in Glocks I would say that carrying with a round in the chamber is more like carrying in condition 1.
