I've never seen one before. My fix sight Six's are all marked Police Service Six as are every other fix sight 4" one I have seen.
Yet this one,sn 150-75163, is a fix sight low back marked Security Six. Have I missed something?

I recall hearing of this before, though I don't recall the backstory. Another Ruger collecting oddity.

Back in the day I bought a four inch, "red ramp" m-58 barrel from parts guy and found that its a factory barrel, and the ramp is not a add on.. The ramp and barrel are one piece with pinned red sight blade. Took it to SWCA meeting and no one had a answer... Asked R.Jinks but he never replied...  |

If I had the extra cash right now, I would go ahead and buy it for curiosity sake. It's listed on Guns.com right now.
It's got high back hogues on it that just look dumb. But I do happen to have some Elephant for a low back. I know $1000 grips on a $650 gun. Been there a few times before.

A 150-75163 serial numbered "Six" series gun dates to 1974.
Model would be a SDA-34 if it's a blued .357 mag 4" gun.
Made in limited quantities.
if boxed,, the correct box would be a solid white, hinged lid, fitted cut-out interior.
There is only (1) KNOWN example of a SDA-34 with the "S" proof mark on the barrel, instead of the normal traditional intertwined Newport proof mark.
So, yes,, they were made,, but in limited quantities.

Asked R.Jinks but he never replied... ***** James.... looks like you hijacked a Security-Six thread, and now you have a co-conspirator. As you know, the Smith & Wesson N-frame M&P Model 58 .41 Rem Mag is the fixed sight version of the M-57. The M-58 barrel is straight, not tapered, with a low, milled steel serrated ramp (your photo appears to show a 4" M-57 barrel). My guess, the red ramp on your M-58 was performed at the Roosevelt Avenue factory as a service. A dovetail is milled in the ramp, with two holes drilled into the base of the dovetail to secure the heat molded insert. S&W would make a red or yellow insert, with red the most common. S&W offered other sight options, including a square plastic “bead” for a Patridge blade, and a Call (flat) gold bead or McGivern (round) gold bead. I don’t remember seeing a red ramp on the low profile M-58 blade. David Bradshaw |

As I recall, and can't remember from where, the first guns were all called "Security-Six" and some time soon after their introduction, they came up with the three different names; Security, Service and Speed-Six.
Might have been from Kuhnhausen's shop manual, but I don't remember where I'd read that for certain.
I'm not sure if this meshes with what contender is saying, but it's certainly not meant to contradict it. I've owned a fair handful of these guns, but never really studied the history.
If I were limited to ONE DA, I'd make it a 3" Speed Six in stainless, with the newer scalloped recoil shield and the older sorta-tapered barrel. Custom, I know, but they will take one heck of a beating, all of mine were accurate and they are very easy to tune up a bit and maintain. Just a tad on the heavy side compared to others, but pretty solid guns in my experience.

When the Security Six first came out (late 1970 was the first production year), Ruger made an adjustable sight Security Six and a fixed sight Security Six. Then, when they were pursuing law enforcement, etc. contracts and had many "remarks" about the grip "feel" of the low back Sixes, they reengineered the frame to what is now called the high back frame and also relabeled the fixed sight Security Six to become the Police Service Six, or for some contracts just the Service Six (IIRC for overseas sales that the buyers didn't want the "Police" marking on the firearm).
The Speed Six, because of the shape of the frame, both low back and high back, has always been called the Speed Six. Some get confused because both the adjustable and fixed sight models of the Security Six came in 2 3/4", 4', and 6" barrels. The Speed Six has only ever been made in the 2 3/4" and 4" barrel length.
As time went on, Ruger did make other various barrel lengths (3" and 5") in the Six series DA's for specific contracts both US and foreign.

How do the frame sizes on the speed/security sixes compare to a GP100?
Is it sort-of the same as a k frame and an L frame S&W?

Yes, similar to the K and L frame S&W's. The frame size of the GP100 is larger than the Six series DA's. On the other hand, the grip portion of the frame is completely different, it is what might be called a stud and the grips are held in place differently. The GP-100 and the Super Redhawk have the same type of grip stud and the grips are interchangeable. The SP101s have a similar grip holder like the GPs and SRH but smaller in size. The LCR also has a grip stud but it's a bit different on its own because of how they are made.
