If you actually owned both a 642 and a G26, you would see that the difference in length is less than one-quarter of one inch. And I seem to remember than the 642 is actually taller than the G26. Most people would not consider less than 1/4" to be "a lot" smaller.
And in fact, the 642 is much, much closer in size to a G26 than it is to a PM9 (which I also own as well). Why is this? Because the J and the G26 are both wider than 1", while the PM is less than 1". Both the J and the G are longer than the PM by close to an inch, and they are both taller than the PM too.
Sounds like you need a tape measure....
