series 70?

[dlay]

Is the sr1911 series 70 or pre series 70, it has solid bushing.

 

[Skalkaho Slim]

It's generally considered a Series 70.

Although I imagine there'll be someone along who will nitpick it to death as to why technically its not. :roll:

 

[DGW1949]

Actually, it is neither.

Otherwise, it would be a Colt! :lol:

Series 70 and Series 80 are Colt terms. Ruger elected to go with what many 1911 makers have done. They use a Titanium firiing pin with different rates on the firing pin, the mainspring, and the recoil spring to give customers a very safe system with fewer parts, thus less chance of failure than a Series 80 system or a Swartz system.

I have a Colt Series 70 and the distinction is the collet (front collar) on the barrel.
It has splits, so it can slide on. A solid collet is probably what Ruger went with. The split types can be unreliable and break. And there goes you gun, probably right when you need it most.3

The collet-style barrel bushing is a difference, but most people regard the firing pin block "safety" parts in the fire control parts as the real distinction between a Series 70 and a Series 80. The SR1911 models don't have the firing pin block "safety" parts.

 

[DGW1949]

So tell me..... If we are to refer to all 1911-type semi-auto pistols which lack a firing-pin block as "Series-70", how are we to draw a distinction between a real Series-70 and all of the other variations of the 1911 which came before it?
If ask that because I presently own an unmolested 1911A-1 and it sure as shootin' isn't a Series-70, nor is it a Series-80. Actually, when ya get down to it, it's not even a 1911.....nor is Ruger's SR1911.

Frankly, I don't see much sense in confusing the issue, especialy when it comes to a Ruger. After all, aint it enough that the terms "Blackhawk" and "Vaquero" are confusing already?

But that's just me.

This is the correct answer. :wink:

It probably isn't apparent, but I agree with you...speaking as the owner of two real 1911s.

I am new to the 1911 pistol. Can you explain why a 1911a1 is not a true 1911??? Are most modern pistol more a1 based? I have the Sr1911 as well as the Remington r1.

"1911" is today usually used as a generic term for the whole family. Most "1911s" are actually made to the 1911A1 pattern, more or less. The smaller pieces can be changed between the two but the major tipoff is the finger relief cuts behind the trigger; these were not on the original 1911s made before about 1924.

Few "1911s" today are made to actual 1911A1 specs, either. Most, including the Ruger and Remington, incorporate several "custom" touches and features that have become popular and pretty much standard in the last 30 or 40 years or so. You almost have to go out of your way to find a true 1911A1 any more, though a few are available.

The SR1911 is a SR1911.

Does anyone know if the plunger tube is cast into the Ruger SR1911 or a separate part, as in the 1911 and 1911A1?
Geoff
Who is a curious fellow.

 

[modrifle3]

Cast into the frame.

 

[dakota1911]

A better question would be does the SR1911 use a firing pin block (FPB). No. Hard for me to call it a "safety"

Series 80 Colts use a FPB, and it is based off the trigger. Taurus and a bunch of others manufacturers use it. Kimber IIs and S&W 1911s before the E Series plus others use the Swartz FPB which is based off the grip safety, and, yes it was developed by Colt in the 1930s. Colt throws confusion on the issue with its new Series 70 with no firing pin block and no collet bushing. The Colt collet bushing was on 5 inch Govs and Gold Cups from 1970 to about 1988, thus yes there were Colt 80 Series with the collet bushing, since Colt introduced the 80 Series about 1983. There were never any 70 Series Colt Commanders; they are called pre 80 Series. I could go on but I think that is enough Colt for now.

It is my understanding the plunger tube is part of the frame on the Ruger SR1911* line.

 

[AEROCOLOR]

How about 1911 based and leave it at that. The different makers and models are all variations on the 1911 platform. Too many to decipher now that everyone has climbed on the bandwagon.

For Colt manufactured pistols there are:
1911
1911A1
series 70
series 80
series 90 (Double Eagle model)

Would the Springfield Armory GI Model comes close to the 1911A1 Specs?................................

For Colt manufactured pistols there are:
1911
1911A1
series 70
series 80
series 90 (Double Eagle model)

And then there's the "Government Model(s)" which were made for the commercial market, but were/are not "Series-70" either.
Traditionaly, Colt's Government Models have been very similar to the 1911A1 of any given era, but with different finishes, grips, and markings. I remember seeing a few early ones that even kept the lanyard loop on the MSH.
And lets don't forget their stand alone model which was made under contract for Argentina....the Model 1927. That one was built with a 1911A1 frame, featured an arched MSH, but retained the 1911 hammer, trigger, and grip safety. Noteworthy also, is it's black (not brown) checkered grips, that all of it's "non slip" metal surfaces were checkered the same as were those of the 1911, and that as-supplied, many were finished in Colt's famous blue...not parkerized.

There are also different variations of the 1911A1. Most notably, the "in service" change from a wide-spur hammer to the familiar skinny hammer, and it's absence of checkering. Somewhere along the line, it also lost it's original 1911-type thumb safety, which got replaced with the same standard safety still used today....which is sans the checkering also.
It aint unusual that military guns exhibit ongoing changes during service. Actually, it is the norm. These changes are/were made as up-grades during arsenal rebuilds, even during war time. M1 Carbines, the infamous M1 "Garand"....they had their share too..yet they retained the same model number throughout them all, as-did the 1911A1.....which to me, calls into question the widely-held concept of what constitutes an "original" gun. As far as that goes, it aint a big secret that some manufactures of war-time guns were using parts from other manufactures to facilitate their own production schedules, and that some (Winchester in particular) were experiencing such a failure rate during testing, that had Springfield Armory not stepped-in to get 'em on the right track, they were in danger of loosing their contracts.....so who's to say that any given military gun has to have all of it's parts marked as being from the same manufacturer, in order to be "original"?

All that may seem like way too much information, but the point is;
There's a lot of variations that can be found within various military model numbers in general, and/or within various Colt model names, but there aint but one "Series-70 Government Model"...so it should be rather obvious that the lack of a FPS does not a "Series-70" make.

Hope this is helpful.

Actually, it is neither.

This.

Series 70 and Series 80 are Colt trademarks. Series 70 designation hasnothing to do with the fire control group, even though it's come to allude to the fact that the pistol doesn't have a passive firing pin block/safety.

Series 70 meant/means that the gun was equipped with a collet bushing and the patented Accurizer™ barrel.

Thus, there is no such thing as a Series 70 Springfield, Kimber, Rock Island, etc. Neither is there any such thing as a Series 70 Commander or Combat Commander. All Series 70 Colts were 5-inch guns...Gold Cups and Government Models.

And there were a few early Series 80 pistols...mostly Gold Cups...that had the Series 70 barrels and bushings. Colt has never been known for wasting perfectly good parts on a technicality, so I suspect that this was the reason for the Series 70/80 hybrids that are occasionally encountered.

 

[eagleeye43]

Just for the record I have three combat commanders, a 45, a 38 super and a 9mm that are series 70 and all have a 70B prefix

 

[1911Tuner]

That tells us that the pistols were built in the 70s, and that they're made of carbon steel with a blued finish. If either of them had been finished in Satin (Electroless) Nickel,™ the B would have been an S...and you'd have thought that it stood for 70 Series.

Until a friend came along and wanted it more than I did, I had a blued Combat Commander with an 80B prefix, and I can assure you that there were no Series 80 parts in the gun.

Colt never built a Series 70 Commander-length pistol. All Series 70s were 5-inch guns.

Here's a picture of the 80B Combat Commander. You may have to enlarge it to see the serial number prefix.
