I got a GSG STG 44 Schmeisser in .22 LR. I got 7 mags with the gun. Of these 6 mags, 3 can only hold 23 rounds instead of 25. Those mags are totally stuck at 23 (and they have 23 rounds not more)... I managed to unstuck a 4th mag to finally hold 25 rounds by pushing a bit harder with a cloth (to save my thumb a bit). This is 4 of 7 mags that don't work well. Is it normal? Did you got issues with your mags?
