When i was in the army i borrowed a m40 for target practise
I shot three mags and then it broke.
Had to send it back to the armory for scraping.
And i used the ordinary m39 ammo.

Later in my club we had a L35 as a "clubgun"
It to shatterd into smithereens.
Both the frame and the slide had multiple cracks.
We only used m39 for that to.

Now i have a Husqvarna m07 in 9mmBrowningLong (9x20)
It's a civilian version made somwhere in the 1930th
Had to change the gripsafety and triggerasembly for safer shooting.
It slamfired a few times, accuatly twice as i thought that
i had the finger on the trigger the first time.
Very easy to disassamble, but when i was to put it together,
that was when the fun started
