I think a 9mm is a poor choice for a silenced defense weapon. The .45 ACP is a better performer in terminal ballistics. A 230gr bullet at 950fps is better than a 147gr bullet at the same. Two things the 9mm has over the .45 is mag capacity and net sound reduction. To be effective, the 9mm must be supersonic which will be louder. Depends on if you want to suppress a weapon a bit or suppress it a lot. Your MEN criteria will dictate.
