I would call it "partially supported" on the left, and "VERY un-supported" on the right.
To me, the .40 S&W is not a well designed cartridge and the original guns were built for police "one time only" use.
The .40 is as easy to load as any other straight-wall cartridge, but it is even more sensitive to bullet set-back or a slightly too heavy charge weight than the 9x19. This leads to LOTS of .40S&W KaBooms.
Then, you have action pistol "gamers" who load it with bullets over 180gn in weight (I remember a couple of reloading manuals from 10 years ago expressly warning to NEVER load a bullet over 180gn in the .40 S&W) with powders at the extreme end of fast burning. Thus, a lot of gamers are shooting a very sensitive and temperamental round well outside of recommended loads.
If you stay at 145-180gn bullets and AA5 or slower powders, you can have a lot of fun with the .40.
For myself, I have a simple rule--IF I can visually SEE any bulge, then that case has been permanently ruined and I crush it. If I can't visibly see the bulge, I run it through my bulge buster. I also DON'T load near max loads and DON'T shoot bullets heavier then 175gn.
NOT a dam thing wrong with the design of the 40 cal,,, just the "glock pistol"..
i have 4 and non of them have ever shown any type of bulge- -
2 star firestar's
a S&W stealth
and reloading is the same as all my other calibers
but i have rebarrelled quite a few "glocks" to eliminate this problem !!!
