Glock didn't destroy the US revolver market. The POLICE market was already in the process of switching over from revolvers to semi autos. Glock did, eventually dominate the police market, for a time, due to their marketing. The civilian revolver market is still very much alive, and since Glock doesn't make revolvers I don't see how you can claim Glock destroyed that market.
Yet the story goes, the US government forced a 10lbs double action revolver company to put a lock on it.
I don't know where you are getting this story from, or why you're repeating it, but those of us who were there know it is completely untrue. The govt. didn't
force anything.
What do people complain about? a 2mm hole nearly covered by the cylinder release. The hole is smaller than the head of the screw holding the cylinder release in.
I don't know what other people complain about, but I do know why the S&W lock disgusts me. It's not the idea of a lock as such, it's the history of how it got there, and where they put it that ticks me off.
A bunch of big city mayors were getting together discussing the idea of suing gun makers because of the violence in their cities. The Clinton administration saw an opportunity to push their agenda. They had a long list of things they want done to guns and requirements for gun sellers, ONE of which was an internal lock. Another among that list was prohibiting anyone under 18 from being in a store where guns were sold. There were a lot of things on their list...
They offered gunmakers immunity from the lawsuits the mayors were expected to bring, if the gun makers signed on to their deal.
The British holding company (Thompkins Ltd) that owned S&W at the time, fell for it. NO other gunmaker did. A lot of people felt that S&W "caving in" to the Clinton's gun control deal was a betrayal. S&W stock plummeted. Thompkins sold S&W for a significant loss.
The lawsuits by big city mayors never happened. The Clinton "deal" fell apart, NO one but S&W signed on to it. (and I don't blame S&W people directly it was the people who owned the company that forced S&W to do it)
The whole thing was an ugly mess and though it took a few years Congress finally acted and removed the threat of lawsuits that the Clintons tried to use as leverage, by passing the Protection of Lawful Commerce in Firearms act.
That "little hole" would be covered by the cylinder latch, so S&W changed the shape of the latch. Functionally, no big deal. But visually a big deal. S&W had kept the latch the same for generations. That made a big difference and for some of us it virtually screams "look here! here's the hole!" And that is distasteful to me.
Other gunmakers have put internal locks in some of their models. In discrete places, that don't change the look of their guns. S&W didn't.
Buy and enjoy what you want, I don't want a S&W with the changed cylinder latch, a lock, or the other changes S&W has made since. Fortunately there's enough old guns to more than meet my needs and wants.
FOR ME, it's not about the mechanics of the lock or its potential for failure, it's about what the Clintons tried to do, and how the owners of S&W at the time went along with it when no one else did.
