Today I fired my Ruger 9 MM pistols using Mec-Gar flush fit mags holding 17 rounds. They performed fine. I got them from Kelleyarms.com for $60. Mec-Gar makes excellent mags, perhaps the best in the world. Many of these 17 round mags look just like the 15 rounders, except that they are marked "Patent Pending" on the bottom.
I also fired a 15 round stainless USA mag, available at $15, and this also worked fine. I had previously successfully tested several of these USA mags. I believe these are one of the best buys in hi-cap mags.
