The new ones seem to be??... I have done some brief test on them, and they seem to take little set, and hold up well.... Only the new type mags with plastic followers are in this category... They are the very best Luger mags ever made.... My upgrades add little, except for looks and maybe a slightly better spring?.... The Mec-Gar mags are a shooters dream, and a collectors nightmare.... Can't have everything!.. best to all, til...lat'r...GT
