Loaded the mag again, went through about 6 rounds and at did it again, then we went through another 2 mags with no issue. Could this just be cause it is new, the ammo is not right for it, or could there be a issue with the gun, my glock 21(45acp) has never had a issue with jamming.

Second I noticed when cleaning both today the spring will sit on a higher spot with less tension or a lower spot with more tension. Is one right and the other not, I had it on the lower spot as that was how it came.
