If it is wrong to have guns and not shoot them, maybe. I have one in my safe for over 15 years and it is also 15 years since I fired it.
I was born in Czech Republic and have it more as a little bit of history. The 52 was in service a short time and didn't see any conflict.
Originally it was made for a Czech round 7.62 x 45 and short time after for 7.62 x 39 do to Rusia. As far as I know, only corrosive ammo was used. They replaced them with vz 58 but I remember that guard standing in front of government building around 1980 still had Chrome plated 52 at there side.
