I believe the decision to discontinue the Six Series was to cut costs.They changed from the full grip frame and added the front cylinder lock while they were at it. If I were to get another GP100 it would be the blued half lug like CraigC's.Every time I see a Ruger Security-Six, I wonder what the improvements were that Ruger felt was necessary to implement in the GP-100? Forcing cone? The Security-Six was designed from the ground up to be a.357, and they are known to digest tens of thousands of hot magnum rounds. Frame stretching perhaps? Nah...even the Speed-/Service-Sixes had no problem eating tens of thousands of rounds with no stretching. Flame cutting? Nope. Recoil? Okay, you got me here, but while the Security-Six was being produced, I never heard any gun writers complain, even in passing, that the Security-Six had too much kick. No one even complained about the S&W 13/65/19/66's recoil. They just didn't hold up to steady diets of hot magnum rounds. How about the triad locking system of the GP-100? Was the Security-Six shooting loose with its locking system? Well, no. They were, and still are, shooting tens of thousands of hot magnum loads and show no problems yet.
So what made Ruger think the Security-Six needed replacing? I can't recall?

The Security-Six cylinder is thicker and stronger than S&W's cylinders.

The forcing cone, although similar in size to the Model 66's forcing cone,
Is nowhere near as robust, and will last much longer!

My favorite GP100 is my 3" fixed sight stainless with compact OEM grips.I believe the decision to discontinue the Six Series was to cut costs.They changed from the full grip frame and added the front cylinder lock while they were at it.

Yes, the Security-Six was pretty much perfect as a .357, with the exception of its out-of-the-box action. It's fine as a dresser drawer gun, but as a shooter it needs help. And fortunately, the fix is as easy as changing its springs. So once I changed the springs and dry fired it a few thousand times, the gun smoothed up considerably.I believe the decision to discontinue the Six Series was to cut costs.They changed from the full grip frame and added the front cylinder lock while they were at it.

Is it my eyes or does the barrel inscription say 36 special in that picture? Granted it's more accurate than 38 special.Is that nice 3" Speed Six a 357? Maybe a GS-33 Postal Service Speed Six. My first Speed Six was a DAO NYCPD 3" in 38spl w/armorer's star stamped on the frame. It now wears the Pachmayr compacts like yours that tame 357s well. Great revolvers!View attachment 957543 .
It does look like 36 but it's a bit lightly stamped on the top. Now a 36 spl Speed Six would be extremely rare!Is it my eyes or does the barrel inscription say 36 special in that picture? Granted it's more accurate than 38 special.
I installed a 10# mainspring and hammer/hammer dog shims on my Speed Six 2 3/4. The trigger pull is light, smooth and 100% reliable through several hundred rounds fired. I found an extra hammer to bob and kept the original intact. You know the GP100 snubs only weigh a couple ounces more than the Speed Sixes. The GP100 may have been in part Ruger's answer to the S&W 686.Yes, the Security-Six was pretty much perfect as a .357, with the exception of its out-of-the-box action.

I can't imagine why Ruger felt the need to beef up the Security-Six. The guys at Ruger could have cut the corners and kept the weight down without adding all the excess steel or changing the balance of the gun.

The Ruger Security-Six has a full frame design whereas the GP-100 has
a shaft (inset).
I'm still kicking myself for not buying a very nice old half lug GP100 (asking $450) I saw three years ago.toyed with the idea of machining a GP100 down to a half or 2/3 under-lug once. best of both worlds? Know that Ruger did have some back in the day. but never seen one personally. Never followed up on the idea as I never had the guts to try it on one of mine. Keep saying someday I'll find a cheap abused GP to try it on... as you can guess. I'm still looking for that.
Yes, what you say is true, but the GP-100s I've handled have completely different balances. The Speed-Six pistols do tend to be smoother due to age and having been shot more, but taking the weight from the grip frame and adding it to the front of the gun gives the GP-100 a completely different feel, and one I don't personally care for. Still, preferences do vary.You know the GP100 snubs only weigh a couple ounces more than the Speed Sixes. The GP100 may have been in part Ruger's answer to the S&W 686.
Well, check out a used Security-Six or Speed-Six, if you can find one.I'm still kicking myself for not buying a very nice old half lug GP100 (asking $450) I saw three years ago.

I love this gun!
Why not just get a Security-Six? After hefting both, the balance of the Security-Six I think is much better.I'm still kicking myself for not buying a very nice old half lug GP100 (asking $450) I saw three years ago.
That's what I always heard. Ruger felt it had to beef up its next iteration of revolver or people would think it would have the same sort of problems the S&W 66/19/65/13 had. It was nonsense of course, but it gave Ruger the excuse to cut corners with the GP100. I tried testing it in the gun store and hatred the balance. It was too front heavy for me. Pointability was awful.The 686 was brought out due the problems the 66 had. At the time Ruger was the smaller company trying to compete with the big dogs and followed suit. Couple that with less handfitting, polishing and investment casting for a cheaper to produce product. Voila! The Boat Anchor 100 was born.
You mean the original grips? They were fine for single action shooting, but people hated shooting it double action. Gun writers said it was a single action gun that fired double action, and that saying stuck. I thought the next generation of Ruger Security-Six was right on. I think the old Speed-Six would sell like hot cakes.We need to start a post card campaign to Ruger. A picture on the front of a Security Six and Speed Six and on the back "If you Build it , they will Buy it." I actually LIKED the 150 series grip frame and grips, myself and thought THAT change was a mistake.
Why would you want only .38? The guy who did my guns reamed them out with a precision the factory just didn't use. I dropped .357 jhp bullets into each chamber and they not only stuck, they stuck at the same place, meaning accuracy would be right on. Let us know what you find on yours. Photos would be nice too if you can.Now you guys have me worried. I am going to have to measure to see if my 38 only is still a 38 only Or did the previous owner have it changed. Hopefully its still original.
According to Bill Ruger, they lost money on the Security Six.That's what I always heard.
