I believe that, as in every other sport, change is inevitable. Whether will see the changes Hopkins suggested remains to be seen. If - and that's a bit "IF" - it ever happens the solution would be simple and inexpensive - .40 shooters can download their ammo to ".40 Lite." I loaded .40s with 155 gr. bullets at MPF velocities for my wife when she first started shooting and we both used it in Production Division with my Glock 35. It was a very pleasant shooting load.
Just my 2/100s of a $ worth.
