I agree that the owner of a gun should remove the lock if they feel it's unsafe and it makes them feel more confident in the gun they are using.

I only have one lock gun, and I won't be removing the lock, mostly because I don't see the failure of a lock as more or less catastrophic than any other parts failure that kept my gun from firing. I've had strain screws come loose or be adjusted improperly by previous owners, and they've kept the gun from firing (light strikes.) True, with a light strike you can go to the next cylinder on a revolver, but it may or may not fire.

I had a N frame lock up because the ejector rod came loose. Had to take the gun all apart because it had gotten wedged so tight. Tightened everything up and put on locktite. No problems since. Haven't sworn off guns with strain screws or ejector rods yet.
