First off, I don' t never use trigger locks cuz it only keeps the gun from firing because it blocks the trigger, and not very well in many cases, I' ve had friends demonstrate that they can get several versions of triggerlocks to fire simply by bumping them correctly...odds you drop them and they get bumped that way are probably low, but I' d rather have somethin that' s keeping my entire action from functioning, I use cable locks or blocklocks in all of my guns. More often than not in some of them, I take the firing pin out and store it with them when on a trip rather than lock them up. That way they can' t be dropped and fired in case I do forget to completely unload (not likely but possible) and I won' t forget a key!

For my cable locks, I do like whoever said, keep a spare in my wallet, plus I always keep my gunlock keys on my everyday keychain, so if I forget my gunkeys, that' s the least of my worries, cuz I' ll have to find a way into my house and truck at some point!
