The locks have never caused me any trouble.
If someone removes the lock, I would highly recommend replacing it before selling or trading it off for liability reasons. When you die, whoever gets your de-locked guns should be made aware of the alterations.
My wife has worked for a very large law firm with offices around the country, and England too, for many years, so we are very familiar with how " victims " lawyers think and the removal or alteration of a safety device is looked upon in both Judge and jury trials.
The locks are a non-issue with me personally, and if I bought a gun that had the lock removed, I would not give it a second thought.
My point being do what you want with your own guns, but "think downstream" when the gun is no longer in your posession.
