S&W .50 Magnum key safety system?

The new S&W 500 ( .50 Mag revolver) apparently has a “key safety system.”

Any idea what, exactly, that is?

I’m toying with getting one (in case my home is ever burglarized by a Cape buffalo or a finback whale, I want to be ready).

The only handguns that I’ve seen with key safety systems were made by the Brazilian firm Taurus, and incorporate a special key to lock the hammer down.

I didn’t realize that Wooly Mastodons lurked about your part of the state, Bricker. :wink:

You ARE planning to invest in some carbon-fiber composite wristguards, aren’t you? Otherwise, you’ll fracture your radius first time on the range. Puts me in mind of that old western ditty…

" Snapped, snapped on the range-
Where the beer and amphetamines reign.
My wrist took a turn, when the gunpowder churned
But the target was blown clean away… "



I’ve dropped a line to a friend of mine who owns one; if no one is able to provide an answer by the time he gets back to me, I’ll relay what he says back to the thread.

One of the European makers (Walther?) introduced a key safety a couple of years ago. There was a little cam in the slide that totally locked up the action. LE letterhead purchasers got a pistol that operated on a handcuff key and civilians got a key that looked like, for lack of a better description, a smaller version of the tool used on the M-14 to lock the metal insert into the wood stock.

A quick search on the S&W website shows no information gave no results for “key safety system”. The Taurus system has a small keyhole in the back of the hammer, just below the thumb spur. Locking it prevents the hammer from moving.

      • I have a S&W that has this system, I am pretty sure all newer revolvers from them do now. I remember there were ugly comments about it on gun boards, theorizing that it might accidentally engage at critical moments, but I have not seen any reliable accounts that this has been a problem. And I suppose maybe there are military/police only models without it, but I don’t know.
  • Also I have heard that the 500 isn’t real bad, not much worse than a good-sized 44. The long-barrel regluar one is a pretty heavy gun, which helps a lot. The shorty 4-incher model is the one that is gonna hurt.

I’ve seen the cam-lock-the-slide system… but I couldn’t figure out how the revolver side of things might be done…

I’m not familiar with the specifics of the S&W system but anything on a double action revolver that prevents the hammer from moving by definition keeps the trigger from moving and the cylinder from rotating. Since all S&W revolvers made sine the very early part of the centruy have a rebounding hammer/hammerblock passive safety it should be impossible to make one fire unless the hammer is released with the trigger being held all the way back at the same time.

Maybe you should consider a GNOM or an UDAR. (Or maybe a nice little Zeliska) :eek: :smiley:

http://www.smith-wessonforum.com More information about the locking system and the 500 than you can shake a stick at including detailed pics. Just search for it or ask.

I hefted one (the long one) at Trader Sports in San Leandro. Heavy, for sure, but I can see the appeal. I felt this odd tingling on my chest while sighting down the barrel. :wink:
Anyway, I’m going to rent one at a nearby range and see for myself what it’s like. Costs $30 for 5 rounds. Not bad.
I have no desire to own one, though. Not that I’ll admit too, anyway.

A word of advice, wear the highest dB rated earplugs and earmuffs. :wink:

I’ve got that covered. Got (and wear) both for my shotgun. :cool:
