Awsome Thread!!! I've been looking for this exact info. I was told by a police officer once, that him and his fellow officers always load their mags to 1 less than full (12 in a 13 round mag etc.). They do this because it lowers the potential problem of a mag spring breaking. Is it common for police officers to do this? Is it common for springs to break? Thank's again, to you all, for the valuable info.
