[QUOTE="1911user, post: 1511162, member: 543"] Full power 9mm loads with 147grain bullets are typically subsonic. You get a full power round to cycle the pistol action and it stays subsonic. A subsonic 9mm round based on 124 or 115 grain bullets would be less than full power (standard pressure) and might not have enough recoil to cycle the action. Also heavier bullets typically penetrate deeper than lighter bullets especially if launched at the same velocity. [/QUOTE]
