Would it be a major undertaking to list the various changes in these revolvers over the years?
Is the info already listed on another site?

I should be able to put together a list of the major changes. Here are the ones for the blued revolvers up to 1994.

In 1931, the first K-22 was introduced. This was the K-22 Outdoorsman. It was made from 1931 to 1940. This revolver has a six-inch barrel with no rib, a Patridge front sight, and an adjustable rear sight.

In 1940 and 1941 (until December 7), the K-22 Masterpiece (six-inch barrel) was made. Only 1067 examples are believed to have been made. This was the first revolver to have the micrometer rear sight. The standard front sight was the Patridge, but it may have Call bead, a plain bead or gold bead.

After WWII, the K-22 was reintroduced. A narrow barrel rib was added. The first samples has six-line serrated tangs. Later examples have the modern ten-line serrated tangs and a wider rib. In 1955, the upper sideplate screw was deleted and the four-screw was born. In 1957, the K-22 Masterpiece became the Model 17.

In 1949, a four-inch version of the K-22 was introduced as the K-22 Combat Masterpiece. It followed the pattern for the K-22 Masterpiece and became the M18. There is also a fixed-sight K-22 M&P (Model 45) that was made for the Post Office.

The M17 and M18 "dashes"

-1: Right-hand to left-hand threading for extractor rod in 1959
-2: Delete triggerguard screw (three-screw introduction) in 1961
-3: Relocation of rear sight leaf screw forward of forcing cone in 1967
-4: Change gas ring from yoke to cylinder in 1977
1982: delete pinned barrel
1986: introduce four-inch heavy barrel for M17; delete M18
-5: New yoke retention system in 1988
-6: Add full-lug barrel in 1990
-7: Drill and tap frame for optics; change rear sight to round base; change extractor in 1994


Introduced in 1990 with a four-inch, six-inch, or eight-inch full-lug barrel. There are two known runs without the barrel lugs, one in four-inch and one in six-inch.

-1: Drill and tap frame for optics; change rear sight to round base; change extractor; change grips to synthetic in 1994
