I, also, don't use trigger locks. Most of them are only secure enough to slow you up for long enough to get killed. If you lose the key and need to get a trigger lock off, then, hand the gun to your kid. He won't have a problem with it. This said, the cable locks work best; but, bolt cutters are able to easily defeat them, too.
All of my principal weapons have the barrels coated with Sentry Solutions, 'Smooth Kote' and are stored with the magazines downloaded by one or two rounds, and in Condition Three. I keep most of my firearms inside a large gun safe with a heavy steel door and mechanical spin-dial lock.
