Too late
I'm hoping Ruger never does this with their revolvers but I've heard they might.
They already do. As far as I know its not uniform across the board all models (yet), but some models already do have internal locks. The New Vaquero is one that does.
However, Ruger did it smart. The lock is in the grip frame, and is concealed from casual view. In fact, if you want to use the lock, you must drill a small hole in the grip panel (pre marked from Ruger).
No ugly, in your face hole in the side of the revolver, with an altered profile cylinder latch that just screams "Look at MEEEEEE!!!!!"
That's what I have against the S&W lock. For me, it ruins the look of a classic gun.
My personal feelings about locks on guns are that they are a feel good solution to a non-existent problem, put in place by and for people who do not understand proper gun safety or storage.
One should not lock the gun. Period. Putting a lock on an unloaded gun serves no purpose at all, and locking a loaded gun is just plain
stupid, and an invitation for disaster. Especially with a trigger lock!
If you need to prevent unauthorised use (gun unloaded), you lock
up the gun in secure storage. Secure the ammunition also, and do so separately. Problem (potential) solved. Or, alternately, you can disassemble the gun and secure critical parts. Again, no problem. And no need for a lock on (or in) the gun itself.
Need to lock up a loaded gun? What on earth for? Guns should only be loaded prior to use. If not ready for immediate use, they should be unloaded. And they should only be kept loaded and ready (unsecured) when you are physically present, or while being worn.
The classic scenario of the nightstand gun, being found by a child and tragedy resulting is the club used by the pro lock crowd to beat us into submission. However, it ignores a couple of basic facts (which have to also be ignored by the gun owners as well, in order for it to happen).
If you are not home, there is no need for the gun to be loaded. If you are not in the
room, there's no need for the gun to be loaded. If it is stored so that anyone can get to it, it should not be loaded. Period.
Their answer is "lock the gun". Not "don't leave loaded guns lying around". Lock the gun! Not gunproof your children, not teach them what guns are and what they do in real life (as opposed to tv), but "lock the gun!"
The amount of time to get the gun lock key, and unlock the gun can be more than the time needed to load the gun. All the modern handguns commonly used for home and self defense today can be loaded very rapidly, perhaps faster than the time it will take you to find the gun key on your keyring, or get it from its storage place.
Add in the infinitesimal (but real) chance of a lock failure rendering the gun inoperable at a critical moment, or the risk of using a trigger lock on a loaded gun, and to me, it becomes something very, very undesirable.
If the gun owner behaves stupidly and irresponsibly, and sadly, many still do, bad things can happen. Forcing gun makers to put a lock inthe gun does not change this. Having a law that says guns must be locked will not change this. Only the actions of the individual owner can change this. And no rule, built in device or law can bring this about.
I don't buy S&Ws with locks. I don't like the looks. I have forgiven S&W for the political decision that made them put them in (it was the fault of the British owners of S&W at the time, not the company people themselves), but I cannot forgive the physical location of the lock, or the damage it does to the gun's esthetic appeal to me. There are enough "pre lock" S&Ws out there to satisfy my needs. Sadly, this does mean I won't be getting a .500 or .460 until/unless they market one without a lock. Oh well.
