Is the mags for the s and w 915 the same as the 5906?

No, the magazines for the Smith & Wesson 915 and the 5906 are not the same. While both firearms are part of Smith & Wesson's third-generation semi-automatic pistol lineup, they have different magazine designs and capacities. The 915 typically uses a single-stack magazine, whereas the 5906 utilizes a double-stack magazine, making them incompatible with each other.
