The spring on new magazines is very tight and presses the top bullet in particular against the insertion lips. Therefore, it may happen that the first bullet is not inserted properly at repeat . If you use ammunition with a ballistic tip, this problem does not occur in our experience. Precision is not affected either. Experience has shown that the spring loosens after a few loads. If you do not want to wait that long, remove the spring and loosen it yourself by compressing it several times.
