I've been debating which magazines to standardize on for my SIG P226. I can get OEM style parkerized 15 round($20) or AFC flush fit 18 round($25) both made by Mec Gar. Are the 18 round magazines proven reliable enough for duty use such as being loaded for long lengths of time? Todd I read a thread from 2009 on another forum where you had reservations on carrying the 18 round magazines for serious use such as duty carry and recomended going with the 15 rounders. Does your opinion still hold true 7 years latter? Thanks.
