    That's not true in the slightest. It will work wonderfully, insofar as to say it will greatly reduce the sound signature, whatever the bullet weight. What he means to say is that you will have the additional sound of a supersonic crack in the distance, unless you use heavy subsonic bullets. 147 grainers are the popular choice. So don't worry, you'll do just fine in sound reduction without the subsonic ammo, but it definitely makes a big difference when you do use it. It should easily be hearing safe without the subsonic ammo, but you will find it to be a lot closer to the Hollywood "pffft" sound with good subsonic 9mm.

    Not exactly.

    You want to use a cartridge/load/bullet combination that (in your gun) keeps the projectile under the speed of sound in order to get the best sound suppression possible and to avoid the sonic "crack" caused by the bullet breaking the sound barrier.

    You don't have to use 147 grain bullets, but it's recommended.

    Just out of curiosity, what's the problem with 147 gr bullets? They aren't hard to find. Winchester White Box comes with 147gr, and they're fairly inexpensive as far as these things go. They can be had at Walmart.

    There is some belief that 147-grain 9x19mm rounds aren't as effective as other bullet weights. Since almost no place allows hunting with sound suppressors, and if you use a suppressed 9mm for defense inside your home, the sonic crack from a lighter, faster bullet won't be an issue, I'm not sure I understand your concern.

    You can also load 124gr bullets to subsonic. 1050fps is fine for 124gr practice rounds. For defense, I load XTP 147gr to the same velocity.

    You will get the best performance out of the 147 gr becuase they will be subsonic. You can run 115 or 124s you will just have the crack of the sonic boom.

    The suppressor will perform just fine with either round. Many folks are disappointed when using supersonic ammo since the suppressor doesn't make the gun "Hollywood quiet".
