I seem to recall muzzle velocity in the 2500-2600 FPS range if I remember correctly depending on what ammo and bullet gn you use. If you are using it for defense make sure you use SP, HP or any other type of expanding ammo. You need around 2400-2500 FPS for FMJ to yaw and fragment. The shorty barrels lose too much velocity to use FMJ for defense. The 10.5 - 11.5" guns are great for CQB to 100 yds with the correct ammo. |
