I bought my M9-A1 from CDNN about a month ago. I absolutely love it. I've read several of the posted topics and most of the tacked threads and have not found this information. Will the older M9 model steyr mags work in the M9-A1? Are they the same mags? Reliability? Thanks, for your help Brain3278
Plus, M40/M40A1 mags will work equally well with M357/M357A1, or vice versa, though I would imagine that mags marked M357 are as rare as the pistols are. Round is same dimensions, .40 S&W and 357 Sig, except for necked-down projectile on 357 Sig. Just showing off, as you asked about M9/M9A1 mags. Can you tell I love my M357A1 and never pass up a chance to brag on it? :mrgreen:
