The .38/44 Heavy Duty revolver was introduced on April 1, 1930. The N-framed gun and the increased-power .38 special made especially for it were in response to police demand for a revolver with more power than the standard .38 special. The .38/44 (.38 special hi-speed) cartridge would be regarded as "+P" today, and it was feared that it would pound the K-frame revolvers unnecessarily. The HD is regarded as the direct linear predecessor to the .357 magnum, and had a shrouded ejector rod similar to the first N-frames (the "triple locks") and the later .357 magnums. In the 1930s, it became the most popular N-frame sold.

These were produced until World War II. In 1941, at the cessation of production, 11,111 revolvers had been sold. After the war, they were resurrected in 1946, using Magna stocks and the more modern rebound slide hammer block. With this change, the serial numbers were prefixed with "S." In 1948, the new short action appeared. In 1957, when model numbers were introduced, the gun became the Model 20. However, only as few as 100 were actually model-marked from 1958 to 1963; the earliest being in 1960. Demand fell off with the popularity of the .357 magnum revolvers, and production ceased in 1966. Post-war production was 20,604 revolvers.

The gun illustrated (a five-screw 4-inch model, serial number S1549xx) was shipped in November 1957, is not model marked, and is in excellent condition. The original stocks, numbered to the gun, are still present.

If you have one or more of these historic Smiths, let's see some pictures!

Here are 3 of my 4 HDs: In the back - a 6.5" Washington State Patrol gun from 1956, in the middle - a 5" first month production gun from April, 1930, and in front - a 4" gun from 1955. Not shown is a transitional gun from 1946. These are favorites of mine, and are all excellent shooters.

I've got a 1937 HD that shows its age and usage. I still like it. And to the OP, the original HDs did not have an "N" prefix for the serial number. They had no prefix at all until the "S" was introduced after the War.

These were produced until World War II; all had "N" prefix serial numbers. In 1941, at the end of production, 11,111 revolvers had been sold. After the war, they were resurrected in 1946, using Magna stocks and the more modern rebound slide hammer block. With this change, the serial numbers were prefixed with "S." In 1948, the new short action appeared.

A few things: the N prefix actually began much later, in 1969, with N1. The last S prefix N frame was S333454, per the SCSW. The change in prefix is said to be inspired by the Gun Control Act of 1968.

The post war transitional 1946 HD was basically the same as the pre war version except for of course the hammer block safety. There were changes with the markings as well, such as the logo being changed and moved to the other side in the post war years. The order for all N frames to have the magna stock actually came before WWII, although I don't remember the year. S62489 is listed as the first N frame serial with the "S" prefix. The short action, which made the revolvers "model of 1950" didn't arrive until late 1949, in November. The post war transitional N frames are S75000 or below from one reference, or S72500 or below from another.

I have two Heavy Duties in my collection. First is a S67XXX post war transitional which shipped in 1946 to Denver CO.

The other heavy duty is a very scarce pre war 4in, which was sent as part of a contract to the Duluth MN PD in 1939.

Thanks for the note! You are quite correct, and I will correct the OP.

The short action, which made the revolvers "model of 1950" didn't arrive until late 1949, in November.

According to Roy Jinks, on page 310 of his History of Smith & Wesson, 1979 edition:

"The revolver remained unchanged until 1948, at approximately serial number S72,300 - when the factory incorporated the short hammer throw into its N-frame line of revolvers."

It might be that the "Model of 1950" label didn't appear until somewhat later.

Well, the Heavy duty did change between 1941 and 1946. The hammer and trigger were not marked with the Pat info. The grips went from the large silver medallion magnas to the high horned style magnas. As it evolved to 1948 time frame and was the ONLY N frame besides the 1917 that was available, the 4" guns went to the straight, no knob ejector rod, from a one line address to a 4 line address; the 5 inch guns evolved to a 5" barrel without any markings on top of the barrel and a 4 line address. All 5 inch guns that I have seen still have the large ejector rod. Roy and I have had several discussions on this subject especially the S72300 as the change over to the 1950 style gun. I believe that the serial number was where they were when the decision was made to go forward. If any of you have a factory short action between S72300 and S75150, I would love to see it and would want to acquire it for my collection. Since all the guns in the range above that I have pics of have long actions and pre war style hammers/trigger, I don't believe that any were made until the early S77000 serial number range.
Just my observations,
Bill
 
When i said that the 1946 post war HD was nearly the same as the pre war HD, I meant to say "the 1946 post war transitional" because of course later in the post war years, the HD under went many of the changes as the rest of the S&W model line. Bill - thx for clarifying and for the additional info.

Bill, for what year does S77000 correspond with for HDs? Do you know of any short action HDs as early as 1948?
