Which magazine capacities are associated with the M17?

• A. 17 and 21 round mags
• B. 15 and 21 round mags
• C. 10 and 15 round mags
• D. 18 and 32 round mags

Answer: (A)

The key idea here is understanding which magazine capacities are actually paired with the M17 pistol. The M17 uses a standard 17-round magazine as its baseline feeding option, and there’s also a longer, 21-round extended magazine that’s compatible with the same grip and feed system for higher capacity. Those two capacities—17-round as the standard and 21-round as the extended option—are the ones most commonly associated with the M17 in training and official documentation. Other capacities listed don’t reflect the typical M17 magazine lineup, so the pairing of 17 and 21 rounds best matches how the weapon is designed and issued.
