-And last i can assure you the use of this Collet Bushing, if you use it on a standar barrel (with not a oversized muzzle), is not so tight but you feel a remarcable diference on the lock up, with out putting much pressure on the 4 spring.
I have use it that way long enough with out problems.
P.D. Believe it or not, both type of barrels have almost the same muzzle size
Odds are that unless you have one of the early Series 70 models where the fingers are thinner, the collet won't break unless you're shooting hot loads all the time which will fatigue the metal.
Both barrels don't have the same muzzle size. I would think they vary barrel to barrel. For example, one might measure .580" at the muzzle while one could measure .582" for example. The same goes for a standard barrel. The Series 70 barrels had a slight flare at the end to create tight lockup. The reason Colt quit making them is that it required for the slide and barrel to be machined parallel enough otherwise those fingers would bind up and break. Therefore it wasn't really any cheaper or easier to do than just fitting up a regular bushing.
