Measuring my Taurus model 605 revolver with a 2" barrel length vs. my Taurus G3C semi with an advertised 3.2" barrel. The revolver is a straight forward measurement of 2". The G3C measuring from the tip of the bullet while being held fllush to the outside of the barrel same position were it chambered, measures right at 2" from tip to barrel muzzle end. Apparently the equivalent barrel length of both of these guns is 2". I would assume then that the accuracy of both would be about the same having same equivalent barrel length. Before having measured both I had assumed the G3C would be the most accurate with a longer advertised barrel. Maybe not so.
