Hi again,
First, there is a K-magnum, whether or not anyone calls it that. From Supica, SCSW, page 137: "The Model 19 is built on a frame that is slightly larger than the K frame in the yoke area."
Second, you implied that the L- and K- frame are somehow radically different, when the differences don't seem any more radical than those within the J-frame. The fact that L-frame barrels don't fit K frames doesn't really change that. I think I established that whether certain dimensional changes constitute a new frame is entirely up to the whim of Smith and Wesson.
Third, you may have your own definition of "transition", but others may not share it. Supica doesn't. From SCSW again, this time the glossary (page 317): "...there is often not a clean break between model variations, and there are sometimes guns produced with some features of both old and new models. These are called Transitionals . . ." Notice that, at least as he defines it, a transitional doesn't have to span one frame or even one model. Hey, the final M66 has "features of both old and new models"!
Fourth:
Because all S&W revolver barrel production changed over to two piece construction.
According to the S&W's website and their 2005 catalog, this hasn't actually happened yet. Most of the all-steel wheelguns (617, 686, 67, etc.) in S&W 2005 lineup still have barrels of traditional, one-piece construction.
Fifth:
So by your logic, and use of the term, the two piece barrel Model 66 K-frame was the transition between the Model 500 X-frame and the L-frame 620.
So, I was saying that a model that combines features of old and new models is somehow halfway in between two new models that are on radically different frames and full of "new features"? Better reread my post.
and:
K-frame .357) is a transition to the L-frame is like saying a S&W Model 459 is the transition from a 1911 to a Glock.
Wha? Since when did S&W make Glocks?
I may be "scrounging up all the self-justification" I want, but at least I'm using facts, rather than declarative statements.
