It is hard to figure out the thinking of these people at Taurus International.
When it comes to the Taurus 692 revolver. Tripple threat is a good idea. 38spl., 357 and 9mm.
Why not a 2" barreled version for carry minus the adjustable sight ? To me a 3" barrel is a little uncomfortable as a carry gun especially if it is of the Compact frame as is the model 617. At times I carry the 617 but to me it is just a little to big for great comfort like the 605.
You really have to scratch your head.
