2 of my guns have an integrated lock. H&K USP and a S&W revolver.

The S&W revolver lock is probably better than a trigger lock, although the key comes with it rusts very easily.

The H&K lock is akward to operate (have to remove the magazine). And a problem is that if the H&K lock is on, you can damage the gun by racking the slide. Not good.

The weird part is that both guns also came with either a cable or trigger lock. 2 locks for each gun?? Guess it's state law to provide the extra lock.

I don't use the locks at all as my handguns are either on me or locked in a safe, but there could be some people that get some use out of them.
