The M9 magazine holds 15 rounds. Any magazine designed to be compatible with the Beretta 92 is capable of being used in an M9 pistol, but the only issue magazines are 15 round non-OEM magazines.
The effective range of the M9 service pistol is about 50 meters, but it can potentially hit targets at distances up to 1800 meters. However, its accuracy and lethality greatly diminish beyond the effective range.
