Hi all,

I've been a S&W owner since 1959 when my father passed down his 32 S&W long hand ejector, nickel plated revolver. I've added several revolvers to my collection over the decades, but just now joining the forum to find out about an uncommon model I'm looking at.

I have been looking on the Internet at a few S&W model 547 9mm revolvers for sale. I looked that model up the the Supica & Nahas catalog and it is listed as being produced from 1980 to 1985. It's listed as having 6,000+ 3-inch heavy barrel round butt, and 4,000+ 4-inch heavy barrel square butt guns made during those years. Don't want to buy off the Internet from anyone with a "no returns" policy so I don't get stuck with something that doesn't work. The catalog lists a different extractor system that has spring loaded fingers that go under the 9mm cartridge rim, instead of using moon clips like my model 25-2. Also, it's listed as having an additional cartridge retainer pin located in the frame above the firing pin to hold the shell casing in place during firing. The firing pin is frame mounted and not on the hammer.

Does anyone have any info about this particular model? Do the special spring loaded fingers on the extractor work properly or is the gun subject to failure to extract due to the small size of the cartridge rim? Are there any type of moon clips available that would work with this revolver?

Any info would help me consider if I want to purchase one of these models.

Thanks,

Rod

Welcome to the Forum.
I've only handled one M547 and that was several years ago. I thought it was pretty cool. The fingers looked kinda delicate to me, but they worked.
Not sure if you could use it with moon clips. Don't think you would want to.

I have owned a number 547s over the years and have never had a problem with any of them. The extractors may look delicate but are quite strong.

The retaining pin strikes the case head at the same time the firing pin strikes the primer. The retaining pin prevents the case from backing out of the cylinder upon firing, remember the 9x19 cartridge is tapered, not straight. Some disagree with this, but it was told to me by a S&W rep. And yes the firing pin is in the frame, not on the hammer.

In previous posts I have attached photos of the two pins, the extractors and heads of fired cases. Will try to post them again but having problems with Windows 8.1

To me, the 547 have the smoothest actions of any K frames that I have fired. Two of my 547s came from Israel as surplus.

If you do a search you will find a lot of information and photos of the 547.

They are cool revolvers

I have had one for many years now.



No moon clips are used for this revolver.

The extractor system works just fine. The only problem with it was the complexity to machine and assemble. A standard extractor and a moon clip is far eaiser to produce.

fixed it for you

Thanks colt saa.

The only one I ever shot had a rather tough double action pull.
The need to drive the case positioning pin as well as the firing pin and to whack the occasional submachinegun primer hard enough calls for a lot of mainspring. A gunsmith told the owner that adjusting to minimum headspace and endshake, plus sticking to US brands of ammo would allow a softer mainspring and lighter trigger pull. I don't think he ever bothered, the novelty wore off too soon.

These were very expensive revolvers for Smith & Wesson to manufacture to fulfill a European, I believe French contract. The beryllium extractor may look fragile but they are not. 547s are very collectable and will only go up in value, I wouldn't hesitate to buy it. I picked up this one in a pawn shop for $275 years ago, the seller thought the hammer spur was broken.

I am certain that I have seen a couple of 547s in holsters of police whilst I was transiting through Charles de Gaulle airport. Never stopped to ask though.

I had a 4" that was stolen, I could shoot it better in double-action than any gun I've owned before or since. I bought a 3" one to replace it, but it wasn't the same, for me.

IIRC the extractor fingers were made out of beryllium copper - tough and rust proof. Supposedly almost unbreakable, no idea why someone would hard chrome or nickle plate them.

I really miss mine; before I left the area I lived in when mine was stolen I answered every ad for one, hoping for the best. It made the detective working on my case (8 other handguns stolen also) a little nervous though

My 4" 547 has the smoothest DA trigger of any revolver I own and is among the most accurate. Really fun gun to shoot

Welcome to the forum!

The 9mm is a much higher pressure round than .38 special. In a K frame revolver you're going to feel that.

S&W makes just introduced 2 new 9mm revolvers, you might check those out. Also, I'm not recommending it, but Taurus makes a current production 9mm revolver. You might be able to locate one you can test fire.

But then, what do I know?

I discovered that the upper pin reseats the cartridge by a secondary hammer blow, initiated by the firing pin being pushed back by the primer.

How did fact come to light you might wonder? Not intentionally! I glued on a trigger stop that makes single action fire rather difficult. So when the hammer comes back, it catches on the single action sear! (Corrected that little drama by giving the trigger a little more overtravel.)



tekarra's (courtesy of colt saa) photos above show most of the details quite well. Note the primer indentations which show the annular ring surrounding the firing pin indent. That flat area is there to propel the hammer back again.




That 3" barreled 547 has been a top performer for me for years. Even shot a Steel Challenge match with it. Was great as long as I did my part!

I had one I picked up for $400.00 a few years ago. It was a 3" and the toughest DA pull of all my Smith's. I did have a couple of issues with the extractors and ended up trading for a 686 2 1/2" and never looked back. Wouldn't trade my 686 for 2 547's. But not everyone has the same taste. Interesting concept but just not my cup of tea. Good luck.

I'd like to find one, but All that I've seen were overpriced. Their owners felt they were FAR more valuable than I did.

I have a 3" with factory RB Target Stocks and I love it.It is one of the few more modern Smith's that I will never part with.Both the SA and DA are smooth and crisp,I have never had a single problem with the extractor.

Would LOVE to find one "reasonably" priced.
will probably never find one

I have used a M 547 (3" round stock) for more than 13 years as my service gun (privately owned) in the French Special Forces. Although I have shot only 1 cartridge in action, I shot hundreds of rounds in training. The M 547 is a fast, accurate and reliable revolver.
The 9 mm caliber was a good solution if we needed to supply from conventional troops in case of ammo shortage during military operations.
The 9 mm cartridge is powerful enough to neutralize an ennemy. I tested it, alas !
The main advantage of a revolver for special operations is that it shoots standard ammo as well as low power bullets. The last is handsome when it is critical to avoid collateral effects; for example inside some bulidings or in aircraft on flight.
As a sport weapon, M 547 is very accurate and its ejection system is very reliable.
In my Unit, at the end of training sessions, a couple of ours used to finish the remaining 9 mm cartridges in an "olympic speed challenge", that is to say when the five targets appeared, we had 7 seconds to shoot five shots, one on each target. In double action, of course. This exercise was most popular in the 1990s but the common weapon used for this contest in Fance was the 22 short DES V.O Pistol designed only for this purpose. Although we were roughly at the same level as shooters, my results were often closed to the top level if we compare with those of my collegues equipped with other revolvers (We had some Manurhin's in 9 mm). I tried the same exercise with my S & W K22 and the results were not that good.
I had had none functioning incident in more than 13 years of use.
As far double action shooting is concerned, I find it easier with the M 547 than with my S &W K22 "Target" with standard 22 LR ammo.

I apologize for my poor English but I am French even if I am a veteran of Desert Shield / Storm and received at the end of the operation the Joint Service Achievement Medal from the hand of Gen. H. Norman Schwartzkopf himself in his HQ In Ryadh.
I joined this interesting forum mainly to answer the question by n4rod105 at the top of the thread.

Let me make sure I understand this. The cartridge headspaces on its mouth in the chamber (the case mouth rests against an edge associated with a reduced cylinder ID) and the retaining pin is required a result of the small taper of the 9mm case, which is subject to set back under pressure.

Sorry, I got mixed up in my terminology.

So the extractor system was originally done for the .45 acp cartridge?

The M547 uses a special one-of-a-kind extractor that allows for head spacing on the rim.

Patent US4127955 -- Extractor assembly for rimless cartridges


The M547 also had a special "backing pin", almost like a second firing pin, that arrested the rearward movement of the fired case. I don't think the backing pin concept was part of this particular patent.

Disregard. Google found the wrong patent. Corrected above.

The 547 revolver is neat piece of ingenuity and engineering. Unfortunately for S&W it was expensive to produce and the mechanism was a bit fragile. It was also a complicated a solution to a problem that they had solved over sixty years earlier with the model 1917. That being said, I would like to own one, but the prices are a little over the top for me.

Since the bulk of those manufactured were sent to France, only the over-runs were sold in the U S, and a few the French evidently surplussed that were re-imported. I have no idea how many were made over and above the original order, but it wasn't a great amount. That's why they bring some pretty fair prices.

I have a 3'' one and like it. Its quite accurate and does not have the kick of a semi auto. The trigger pull on mine is a bit on the high side and from what I have read many are. They have to fire NATO spec ammo and needs a bit more oomph to hit the locator pin that secures the cartridge when its fired.

I got mine at what I thought was a reasonable price. Was looking for a long time and a GS about 50 miles away took it in on trade. My son spotted it in the case and gave me a call and I went there ASAP and got it. I do not think they knew what that gun was worth.

In the world before the internet a lot of us S&W accumulaters had a sub to Shotgun News. I distinctly remember the J&G(AZ) ad for the 4" 547 @ $179 and if I remember right $20 more got you a three inch. At the time I was chasing something else but that ad lasted about 4 months for the 3" but almost a year for the 4". The LEO world was going to semi auto and the prediction was revolvers would be useless! Pardon we while I kick myself again&again&again

I would sure like to have a 547! I think that concept is neat. On the flip side what would it do for me that my other Smiths can't do? (I know fire 9mm in a revolver) If 1 happened by me at a reasonable price I would have to do it. Bob

I bought my 3 incher new in 1983 and while I haven't shot thousands of rounds through it, it does work just as advertised. HKS made speed loaders for it.

I used to encounter a fellow at the range who had one and shot a coffee can full of his 9mm reloads through it each session. He had thousands of rounds through it, he said without a bobble.

One day, he had some Austrian Hirtenberger ammo and was shooting it. This stuff is very high pressure and was intended to shoot in blow-back submachineguns, not handguns. He shot six and the empties wouldn't eject. He pounded on it with everything he found on the range. Eventually the copper-beryllium fingers tore their way through the stuck brass casings without budging them! He called it a day and went home. Next time I saw him, he was shooting it again. He said he took the cylinder out of the gun and used a steel rod from the front of each chamber and a framing hammer to beat them out. It didn't bother the ejector mechanism.

Numrich used to carry the parts for the ejector.

S&W discontinued the .45 ACP Model 25-2 about the time the M-547 came out and a lot of us hoped to see the .45 reappear in the catalog with a M-547-style ejector system. Didn't happen, of course. The moon clips are probably the better, simpler and way cheaper was to put rimless cartridges on double action revolvers.

I would dearly like to see Model 25 with 547 style ejectors to go with my 547s.

Owned a RB 3" when they were brand new. Never saw the appeal.

I could buy a 3" M-13 and have way more power, or load .38's. Or buy a 3" HB M-10....and shoot .38's. At the time nines were not the ubiquitous round it is today. They were more expensive than .38's and at least my gun wasn't all that accurate.


Sold mine and really don't regret it.

If you still have your 547 I am looking for one to purchase. Let me know if you know of any you would be interested in selling. Thank you
