I'm incredibly biased, but I think you just can't go wrong with a K frame S&W 22. The one all the way on the right is my Model 17-3 that I bought brand-spanky new in 1975 for the then princely sum of $125. The rest are various K-22s (the predecessor to the Model 17). The one in the middle is the best shooter of the bunch, a K-22 Outdoorsman from 1932. The finish is a bit worn, so I was able to get it a few years ago for $500. Because of the finish, the serious collectors were not interested. I had it lettered, and it was shipped to the Providence Rhode Island Board of Public Safety. Roy Jinks thinks it was used by a police pistol team. It was sent back to the factory in 1946 for a bit of a tune up. Like I said, it is the best shooter of the bunch.
Sorry, I just can't get excited about the Model 617. I bought this Model 617-6 used a few years ago. It was made in 2003. I just think the full underlug of the barrel is UGLY. Really front heavy too. I bought it because I stumbled on it at a local shop, I did not yet have any MIM guns, and the price was pretty good. I was shooting some steel plate matches back then and I needed to put eight rounds onto a steel target really fast. Could not do that with a six shooter, but this ten shooter made that possible. But after shooting it a few times it never comes to the range with me anymore.
Compare that ugly thing to my Model 17-3. The 617 can't hold a candle to the Model 17. And the action is better on the Model 17 too.
Smith and Wesson still catalogs the Model 17 in their Classic line. The list price is $989. For that you get MIM parts, the lock, and laminated wood grips. There are still plenty of nice old Model 17s and K-22s out there, made the old fashioned way. You just have to hunt a bit. You will get a better gun for your money.
The story on the Kit guns is way back in 1902 the only 22 rimfire revolvers with swing out cylinders that S&W was making was the tiny M frame Ladysmith. Forget about those J frame things S&W is marketing today that they call Lady Smiths, they ain't Ladysmiths. The Ladysmith was a seven shot double action revolver chambered for 22 Long, not 22 Long Rifle. This one is a 3rd Model Ladysmith that shipped in 1910.
Anyway, in 1911 a San Francisco gun dealer named Phil Bekeart got the bright idea that a 22 target revolver built on the I frame (bigger than the M frame) would be the bee's knees. The I frame was designed to be the right size for a six shot 32 caliber revolver, smaller than the K frame. S&W wasn't so hot on the idea, but agreed to make a production run if Bekeart would buy all 292 guns in the production run. Because the guns were built on the 32 sized I frame, but were chambered for 22 rimfire, they were called the 22/32 Hand Ejector. Also known as the 22/32 Heavy Frame Target, which is really funny because they are quite a bit smaller than the K frame 22s. But K frame 22s didn't happen until the 1930s, so Heavy Frame it was. They were also known as the 22/32 Bekeart in honor of Phil. This is not a 'true' Bekeart, it shipped much later in 1940, but this is what they looked like, with the grips that made them big enough to shoot accurately.
This photo shows the relative sizes, top to bottom, of a K frame K-22, I frame 22/32 Heavy Frame Target, and a Ladysmith.
In 1935 S&W started making the 22/32 Kit Gun. Still built on the I frame, it was a six shot 22 rimfire pocket revolver with a four inch barrel. They were called Kit Guns because they were the ideal size to bring along on a camping trip or in a tackle kit. This version was made until the start of World War II in 1941. In 1946 production started up again with the Postwar 22/32 Kit Gun, still built on the I frame. These were made until 1952.
In 1953 S&W introduced the Model of 1953 (duh) 22/32, built on an improved I frame with a coil main spring and an improved hammer block.
The J frame Kit Gun finally showed up in 1955 with an aluminum frame. The J frame is slightly longer than the old I frame and has a more elongated trigger guard. Still a 32 caliber size gun.
When S&W went over to a model number naming scheme in 1957, the 22/32 Kit Gun became the Model 34.
This Model 63 22/32 Kit Gun was made around 1980. Like all Stainless S&W revolvers, the first digit in the model number is 6.
Sorry, I don't have a comparison photo showing the J frame Kit Gun next to a K frame Model 17, but the Kit Gun frame is pretty much the same size as the Bekeart, except it will have a four inch barrel.
Although the 22/32 Kit Gun is an ideal size to put in your pocket while hiking through the woods, I don't seem to do that very much. I can't remember the last time I shot my Kit Gun. But I shoot my K frame Model 17 and K-22s all the time. Being a bit larger and heavier, I find they are perfect for bouncing soup cans around at the 25 yard berm, as well as serious target shooting.
