My dad was issued a Stgw 57 when he entered basic training.
After finishing his military service in 2000 he kept it (converted to semi-auto) and passed it on to me.
It's been sitting in the gunsafe for the last 7 years because it's a heavy piece (6,5kg) of #### that's an ergonomical nightmare (for example: fold down-sights!!).
I don't like shooting it and only keep it because my dad carried it in his 20 years of military service.
