Simple question, hoping someone knows just off the top of their head. I have both Mec-Gar marked and Sig Sauer only marked 13 round 9mm mags for the 226. I didn't pay attention when disassembling for cleaning, and noticed that one or the other has longer springs. Followers and magazine base plates all appear to be the same. Any clue of which magazine body gets the longer spring? If so, why is one longer than the other, for the same marked capacity?View attachment 7250632View attachment 7250632View attachment 7250632
