Ok, I apologize for my reply sounding dismissive.
I was thinking of the history of the "40 cal's" in general.
The .41 mag was developed as "the ultimate police caliber," back when revolvers were standard issue firearms for LE. It was more powerful than the .357 and not as heavy recoiling as the .44 mag.
Then along came the "wonder-9" 9mm as well as many LE agencies switching to semi-auto designs. Many felt the 9mm was not the best caliber for LE work, and many also felt the .45 was "outdated." So,, the 10mm was developed as a semi-auto caliber for LE work,, to do the same as the .41 mag. But it too was pushed by the wayside,, about the same way the .41 mag got shunned by many in LE work. So,, along came the .40 S&W which is a shortened .10mm,, and it got accepted by many LE departments,, as THE caliber to have AND it was in their preferred types of firearms,,, the semi-autos.
Sadly,, budgets,, and expenses,, (along with recoil sensitive non-gun types who failed qualifications a lot) have made many LE departments go back to the 9mm,, thinking it'll be "ok." They fail to heed the lessons of history.
But in the recent years,, the gently demanding public has wanted more 10mm handguns,, and with the increase in demands,, more companies are now building 10mm handguns. And a FEW companies do chamber revolvers in 10mm to satisfy the desires of many who wish for a companion revolver to their semi's.
Now,, I know you most likely already know most of this,, by the fact you seem to enjoy the "40 cals" in general. But I seriously doubt that modern times will provide enough demand for a rimmed 10mm. Thank the newer generation of gun owners who think revolvers are "outdated."
BTW; I have some .401 brass & such,,,, just no gun in that caliber.
