70 G Series

What is the difference between a "Pre" series 70 and a Series 70 besides the collet?

This is a safe queen with fewer the 100 rounds fired.

Estimated value, trade for a similar condition, current production 9mm S/A Range Officer?

Thanks,

John

The only differences that I know of between a pre 70 pistol and an "EARLY" 70 series pistol are the collet bushing, the stocks and the roll marks. The Colt verified proof mark may have been moved as well. Also, differently marked magazines with a weep hole were introduced but I don't know when.

What filson said is correct. With the pistol you pictured the trigger and grips have been changed by a prior owner.

Regarding vintage 1911s, pre-1970 pistols are highly collectible in original, unaltered condition and should NEVER be refinished or modified as it completely ruins their monetary value.

Yup, I replaced the short trigger and "cleaned up the trigger break" but I can put the short trigger back in.

What stocks came on these? I think around 1972?

I have some really nice rose wood with medallions.

Is this in the $850-950 price range?

The original grips were sandblasted, lacquered walnut with sliver medallions. Not checkered.

Trade that for a made in Brazil framed Springfield? Come on man!

Wow, that right side slide roll mark on your piece looks way too low.

Springfield 1911s have not been made in Brazil for some time.

Of all the 1911s I have worked on in the past year, Springfields have the best fit barrels of any. That includes Colts, Kimbers, Ed Browns and Les Baers.

In fact, Colts have consistently been the worst with typical loose breech of .020".

OK, the sand blasted stocks! They should be easy to find.

That explains the replacement grips!

Thanks again,

Didn't the S70s also have the Accurizer barrel that went with the collet bushing?

The barrel and collet together made up the 'Accurizer' set-up. The special barrel is frequently overlooked but is critical, because it was machined behind the muzzle to a smaller diameter so the gripping fingers of the bushing could relax, allowing for easier manual cycling of the slide.

This 70G has the collet bushing!

Thanks,

My GC has the collet bushing and hasn't been a problem but I retract the barrel a little before turning the bushing!

I think your estimate is about right. in order to worth more, it would have to be near perfect and totally original, with the original box, book and papers. I don't know if it would be cost-effective to spend anything on it because it might not get you more in return. Many don't like the early 'large roll-mark' models and the correct grips are pretty ugly.

I assumed it did, but it's good to know.

The original Series 70s were distinguished by the collet barrel bushing and matching barrel with a slight step-down behind the muzzle as 1saxman described. A lot of people don't realize that the collet bushing system wasn't discontinued until around 1988, so early Series 80 pistols have it as well. The current trend of calling any 1911 w/o a firing pin safety as a "Series 70" probably began when parts manufacturers like Wilson Combat and Kings Gun Works had to distinguish between parts they made for Series 80 models and Series 70 and earlier, like firing pins and extractors. Eventually everyone started calling anything w/o a FPS as Series 70, which was technically inaccurate. Unfortunately even Colt rolled with it and now calls all their pistols w/o a FPS Series 70 models.

Oh well, it was their name to begin with so I guess they can use it any way they want.
