I just picked up a used Colt MK-IV Series 70 yesterday. I can't get this fucking thing apart. I can't move the barrel bushing more than 1/8th of an inch in either direction. Is there some secret to taking these things apart that I should know about? |
Don't tell me that shit. Alls I got was the damn gun. I don't have a bushing wrench. [mumbling]Stupid Colt....damn springfield never needed stupid bushing wrench[/mumbling] |
I think that one opens bottles too! |
Clam down that is the way it should be, it is a good thing the bushing fit to slide is tight. |
| It's fit nice and tight, paople pay EXTRA to get that, be happy. You don't have to take it out to break it down anyways, Make sure it's unloaded, remove mag, line up notch and hold in place with hand, remove slide top, remove slide, Take out spring and plug, it'll be easier to put a drop of oil and work it back and forth. It'll come out. |

I own 7 1911's and I don't need no stinkin' bushing wrench to take any of them apart, even my Wilsons. Just push the end of the spring tube in and turn the bushing with your fingers. Any woman could do it.  If all else fails, just remove the slide stop and take the slide off while under spring tension. Then unlock the barrel and remove the bushing. |
| OK, Ikor in the 1911 forum helped me out. It seems that this bushing is some kind of fingered bushing, and that the barrel is stepped. I had to pus the slide back about 1" to turn the bushing. After that I was able to remove the actions spring, the slide stop and slide. Can't get the barrel out of the slide, because this bushing is stuck in there. I don't know who invented this, but if it wasn't the Devil then it was one of his close friends!!! |

you might try backing the slide back a bit and then trying to turn the bushing also the mag, empty, can be placed along side the bushing, using it as a comealong to put pressure on the bushing while pushing down on the spring retention "button" the "wrench" is not a "needed" tool, just makes an armourers life a bit eaiser  ..the gun is meant to be broken down using its own parts as tools mag floor plate should remove grip panel screws. slide release will push main spring pin out etc.. I used to know them all but,  ,I got old, sorry
|
All full size series 70's 1911's had that collet bushing. |
OK, I got it all apart. This design is fucking weak! I hope that someone was made to suffer for this...other than me. |

Well, I can always drive by and pick up that peice of shit for free, you know. Save you the trouble with it and all... 
|
Pssssst..... Glocks don't need no steeeeeenking wrench

The collet bushing was never even a design of JMB. It was a blaspheme by Colt in an attempt to fix a problem that did not exist. Just like the Series 80 firing pin safety. Bullshit, pure bullshit. I think if anyone should suffer for mocking JMB it should be Colt for continuously screwing with a perfect design. |
|
| The downside to the collet bushings is they flex to tighten up the fit between the slide/collet/barrel. The flexing will sometimes lead to the fingers of the collet getting work hardened and eventually snapping off/breaking. A solid bushing is better in this respect. The collet style bushing was Colt's answer to getting away from fitting a solid bushing to the pistol. |

Get a Bushing Wrench! Specially used for tight bushings on 1911's. I have Springfield Armory 1911 i customized myself using a Ed Brown target barrel and bushing, that bushing locks in their tighter than a "ticks ass"!!! But damn those 1.5 inch groups at 25 yards look good!!! 
|
It's both The other one is without the bushing wrench, and instead has a device for assisting girly-men in opening beer bottles with twist-offs. |
It apparently uses Colt's collett style bushing, which was a rather bad idea in my opinion. You can find standard barrel bushings that will fit your barrel if you want to change it out. That being said I never had a problem disassembling my Colt with the collet bushing. |
Yea, with a Glock you have to pull the trigger first. But field stripping can be done 5x faster than a 1911. Someone posted pics last year when they started to field strip their G21, and a Gold Dot went through their hand. |
That person was an idiot then. There isn't any reason put your hand in front of a Glock barrel. Not to mention doing a chamber check first. |
 First thing everyone wants to do is put a wrench on things - - - guess how things get broke?1911 FAQ & LINKS

I agree. Stupid should hurt. I guarantee he won't be that stupid again. There is no excuse for not clearing AND checking the chamber. That just retarded not too. |

www.sightm1911.com/lib/history/s70_colts.htm I did not know that. The Collet Barrel Bushing Human nature, being what it is, will always lead some to search for the best of all possible worlds – match accuracy and 100% combat reliability. It was this quest that led to the most distinctive innovation of the Series 70 pistols: the collet style barrel bushing and it’s accompanying barrel. Prior to the advent of the Series 70, Colt auto shooters had two basic choices: the very tight, target-tuned National Match or the M1911A1, albeit repackaged and finished nicely. The Series 70 attempted to hit the middle ground between the National Match and the M1911A1 by delivering better accuracy than the M1911A1 and better service reliability than the National Match. The Series 70 Collet Barrel Bushing  Accuracy in an autoloader comes from a consistent barrel lock-up when the gun cycles and reloads itself. If the front of the barrel is wobbling around, the lock-up will not be consistent. In the M1911A1 this means having a barrel bushing which is closely fitted. Colt engineers were faced with a choice: either they could hand-fit the bushings and thereby create a prohibitively expensive manufacturing process, or they could design a bushing which, in essence, fitted itself by its shape. They chose the latter and the collet bushing was born.  The Series 70 Barrel. The area above the red bracket is the raised part of the barrel which contacts the bushing The collet barrel bushing has four “fingers” rather than the solid tube of the G.I. bushing. The "fingers" exert a sort of spring tension between the barrel and the slide to produce a better lock-up. The Series 70 barrel is raised slightly in the area where the bushing makes contact with it. The collet bushing, like every other modification of the original Browning design has proven to be controversial. While it does deliver improved accuracy, its design made it prone to breakage. Also, it fits much more tightly than the M1911A1 bushing, making it harder to remove and many gunsmiths advise pulling the slide back about an inch or so to relieve pressure on the bushing before removing it. |
Series 70 Commanders and LW Commanders are an URBAN MYTH ! The 70 in the serial Number has ABSOLUTELY nothing to do with being a Series 70. It doesn't say MK IV series 70 on the slide like the Government model does, does it? It does not incorporate the stepped barrel and collet bushing which makes a Series 70 a Series 70. Colt NEVER made a series 70 commander, the commanders and lw commanders made during the same time frame as the series 70 Government models are identical to the commanders and lw commanders made during the PRE series 70 Government model production. ALL Series 80 commanders and lw commanders have series 80 rollmarked on the slide. With the exception of the 1991a1 models. |
Yeah.... you're probably right. Colt added the "70" serial-number prefix to the Combat Commander and Mark IV/Gold-Cup for no reason at all. It's just a coincidence.  
|
........... It's pretty easy to be flippant to hide the fact that you don't know what you're talking about. If your thesis is correct then explain why their is no 80 prefix to this Series 80 Colt.
