Covan, Sir!
Strikes me as that your senior advisor was a quite "practical oriented" kind of officer, and pragmatic regarding "on the jobb" versus "when the brass lurks around to inspect shoeshine and other things...".
A little "trivia" however, regarding the M/45 submachinegun. The modell known as "Swedish K", is actually more precisely either "M/45B" or "M/45C". There was some modifications to the "A"-version which prooved to be neccessary. You can see a rather extensive information regarding the "Swedish K", by link:

When I did my mandatory part of my service, we were picked out to "play russkies" at an exercise. Our Captain was also a rather "unconventional minded fellow" (and notorious amongst his fellow officers for his ability to perform practical jokes against them), and he ordered us to "sideways insert" 1 extra recoil-spring in to the one already belonging to the weapon. So by this, there were "2 layers" so to say, of recoil-spring in each of our M/45's. When standing at a distans, the sound from when fireing the M/45, was almost indistinguishable from if instead being a 7,62mm beltfed machinegun. The firerate was quite interresting, to say the least. Only problem however was that, at times, the springs did not allow the "pin-box" (I do not know the English word for this part of the weapon) to go far back enough after having fired 1 round, to hok up in locked position. As a result, when pulling the trigger once, the whole magazine was emptyed at once, even if letting go of the trigger. But as we had A Lot of "blank ammo" with us, it was not a "logistical problem" for us though... Those 10 day were actually quite fun! We almost scared the you know what out of the ones we "jumped". 1 such "station" was actually manned by female "contractee-reservists", and we were of course a little "nicer" when we attacked them. (Secretly hoping for that they would take us prisoners. Saw several of them, and quite a few were very good looking! You know, typically "Swedish blonds"...).
Rambling service-memories now I realise.... Best end here. T G C!
Sincerely
