The 17 round mags have ran great for me with the XGRIP adapter. Unlike aftermarket mag extensions I have no problem using the XGRIP since it’s a non critical component for the gun to fire. The 9c being my first handgun purchase and primarily my choice for CC. I also wanted something that could serve as a bedside gun at least temporarily. I purposely bought the 9c so I could carry by day and at night I simply loaded a 17 round mag. Fast forward a few years after being bit by the gun bug and I have more options. I still keep the 9c loaded with a 17 rounder when it’s at home.

The 17 round mags made the range visits better for a new shooter like me. Now I simply enjoy the versatility of shooting the 17 round mag at the range. I never intended or have tried carrying it, but as far dependability goes in combination with the 9c.

Same experience for any S&W mag I’ve ran in the 9c. Always feeds and the gun goes bang.
