It Always Trips Me Up

.357 Magnum dates from 1934.

I know this.

I've known this for years.

But every time I see an article on George S Patton's S&W Registered Model I'm all like, "they didn't have .357 Magnum in WW2!"  George bought his in the first year of production.

Note the grip adapter!

But they did.

I think it's because S&W essentially still makes the same gun (or at least one that looks a lot like it at a glance).
