Looks like a straightforward fix for the mag issues with the ACM PPSH.
excellent find and love the fact of mid cap drums in 2 months.
Havent had to do what the video suggest, but i found gutting the spring mech and replacing with a TM or something decent, and removing the food(yes, i found food in mine!) from the mag, and its worked great since.

My armoury;
Tanaka Kar98(1942 woodwork and parts), M1 Garand AEG(1940's woodwork and metalwork), MG34, SVT40, Mosin Nagant M44, MP40, PPSH41, Luger and PPK.
Awesome I'll give it a try in a few mins.
Well it took a little longer than anticipated to even start the fix... other stuff came up. lol.
Anyway. it's now done and I just emptied a mag without a single misfeed... the first time that's ever happened.
It took extra time as you really do have to make sure that you file 2.5mm x 5mm off that bit... in fact I may have gone further.
As far as I can see it was snagging on one of the cogs in the mech from time to time...
