Remember: it says above "such as" a trigger lock.
A suggestion is implied.
Example: If pull my Ruger Mark III's bolt all the way back and put a padlock thru the slot, I've effectively rendered it 'inoperable'.
If I do the same thing to a 1911 and run a cable lock down thru it - same effect.
If I swing a d/a revolver open and put a padlock thru the top strap --> inoperable.
Single action revolver? You'll need a long-padlock for this -they're cheaper than a trigger lock-... Remove the cylinder and put the lock down thru a chamber and then put it thru the frame's window. Your cylinder is locked to the frame. And, it's every bit as inoperable as it would be had you used a cumbersome trigger lock.
Trigger locks are but a suggestion. There are lots of ways to render your h/g inoperable.
[it should go without saying but here goes anyway: you can't leave the key in or near the lock!] If that sounds ridiculous to you, well - you'd be surprised...
Finally, remember that it is impossible to transport a firearm of any kind in an unattended vehicle.
That is to say, you can have your handguns, so long as they've been properly rendered inoperable, inside a duly locked box sittin on the front seat next to you and be OK --- until you leave the vehicle.
