Hi everyone. I purchased a new .40 SC yesterday, the dealer installed new Wolf mag springs in the 2 regular and 1 extended mag that came in the kit. Anyway, he told me, as a rule of thumb, always load any mags, regardless of pistol / mag type, with 1 less round than the mag's actual capacity. As an example, the extended mag carries 12 rounds, so never load more than 11. Feedback please. Thanks !
