That article does a fair job explaining the difference between the series 70 and 80. So what “series” are the Kimber types that have a completely different barrel bushing type?
There are, of course, complications with those designations. Modern Kimbers are basically Series 70s with something called a Swartz Safety installed that is somewhat similar to the Colt Series 80 firing pin safety changes. Older (pre-”Series II”) Kimber designs are straight up Series 70 designs and have no firing pin lock/block at all.
The ‘Series’ designations only strictly apply to Colt products. Other manufacturers adopted some, all or none of the changes between the Series. For non-Colt products, mostly the terms are used to distinguish between ones without a firing pin safety and ones that have one of some kind. It’s kind of a genericization, much like Kleenex or Xerox.
