I heard the hammer was shortened because it would come back when fired. Any truth in that?
Thanks for the info.

...well, yes. I heard the same thing. I suppose that if a round was loaded hot enough, the designers suspected that the 'bucking pin' might cause a violent kick-back of the hammer and may pinch the web of the shooter's hand. However, I think this was a CYA type thing on their part.
You must admit, it has a weird shape to it.

{As pointed out by TEKARRA in post #31, the hammer is 'bobbed, not shortened}.

You have to look at it's history to understand the 547, it was developed for the Israeli's to arm a police department they did not want to issue autos or even moon clip revolvers to, I believe it was Lebanese. The idea being to limit their firepower since they were not trusted 100%. There is no such part as a bucking pin, the positioning pin and heavy trigger pull (stout mainspring) were design features incorporated to allow reliable function with hard primered 9 mm such as Egyptian. S&W met the design goals but it wound up being so expensive that the Israelis backed out. I agree it was an elegant solution, unfortunately it was too costly to produce for it's intended purpose.

I saw this odd thing on the web the other day. Interesting But not as nice as your 547 that is one sweet revolver. The Korth is actually kind of ugly...as sin.

I initially missed your mention of the sky marshall, but posted a link and picture of it below.
No. The 547 was not made in stainless steel. This is one that I picked up at a gun show a few years ago and the finish is satin nickel. Also note it has a 4" barrel and the butt has been rounded. Somewhere on forum is a photo of another 4" 547 that has been plated but has the square butt.
Not that I have observed. I am not sure as to why S&W bobbed the hammer but it sure makes it easy to spot.
I disagree with part of your statement as I have two 547s, a 3" and 4", that I purchased in the 80s that were brought back from Israel. The importer, whom I knew quite well, said they were originally issued to an Israeli police force. The same person also imported a large number of Israeli surplus FALs.
I will have to look through my file as somewhere I had a copy of the S&W patent application for the extraction system.
The limit pin was intended to prevent the tapered case to back out of the cylinder during firing and hit the recoil shield thereby binding the cylinder. This function can been seen on the photos of the fired cartridges.
Although I have not measured the trigger pull of the 547 against any other K frame trigger, I do not think the trigger pull of the 547 is any heavier than any other K frame revolver. This is purely a subjective observation. Having said that, I find the trigger pull of the 547 such that I shoot them more accurately than my other K frames.

Another comment on the issuing of the 547. I have heard the French had approached S&W for a 9 mm revolver but have nothing to substantiate this claim. However, in Charles de Gaulle airport I have seen some bobbed hammer revolvers in the holsters of the police.
Also of interest is that Ruger developed a revolver, maybe a Speed Six, in 9mm with a spring extractor for a European police customer. I have seen a photo but not an actual revolver. I have heard it speculated that Charter Arms used a modified version of the Ruger extractor for their current revolvers in 9 mm and .40 S&W but have no fact for support.
Whilst on the subject of 9 mm revolvers let us not forget the Barracuda which was designed by FN and produced by Astra that had a convertible cylinder to fire both the 9 mm and the .357. I came upon one of these back in the 80s but alas, it did not have the 9 mm cylinder.
I have been a bit long winded here, but I find 9 mm revolvers and particularly the S&W 547 interesting.

Here's a copy of the first page of a letter from Roy Jinks regarding the 547. It isn't my letter but rather one I saved some time ago, possibly from this forum. I have no knowledge of the Israeli connection, but I distinctly remember back in the eighties when the dealers were blowing them out and the story at the time was they had been produced for a European police department. That was when high capacity autos were coming into their own and that was what the department ultimately went with, leaving S&W with all these 547s. You could pick one up for less than $200 back then. I think I paid around $187 for mine.
I know that the "Bucking Pin" will drive the hammer far enough back to engage the SA sear notch. It happened to me several times after gluing on a silicone rubber trigger stop.
Shoot. And the hammer's "still" back! ?? Pull trigger (hard, as the rubber stop needed compression as well) and click. ??? Of course, not being a SAA type, the trigger must be actuated to turn the cylinder! A minor trimming of the stop allows the hammer to fall back forward normally now. One would have to think it would be quite effective in driving the fired case forward! (But it's an unneeded feature. Never had any of my other 9mm revolvers get cylinder bind, so...)
This little trigger stop led to the surprise "second strike" feature for a short time.

The 940 (either one, usually the primary ugly one), not always. Sometimes I just pop 'em out with a cleaning rod or flatblade screwdriver. Have never gotten around to making a demooner for it, so just dropping in individual rounds is convenient on some longer range sessions, or if I'm stupid and forget spare clips!
The 986 is still NIB, due to weather and work, and the 929 has only been out once. Thinking they may not do clipless well, as they don't seem to have sharp shoulders at the front end of the chambers.
Where the Bucking Pin would have been stellar is with the .22 Jet. (If I was mad, I'd consider doing a barrel and cylinder swap between the two, but it would only useful for function testing. (Mixing fixed and adjustable sight frames...)
ETA: It occurs to me that the Jet has the weird swap hammer and dual firing pins. Maybe a flat face hammer and a replacement of the rimfire pin with a bucking pin would work! Coolio. Beryllium copper isn't a problem, have some from other firing pin replacement projects...

While I agree the Korth is ugly, it's no worse in appearance than the ruger lcr or some of s&ws performance center models. If the stupid accs rails were removed it wouldn't be nearly as ugly though
