I'm still new to the suppressor world and got myself familiar with the rimfire stuff, but now I'm on to 9mm and soon .30. Want to drop some coin on a fair amount of 9mm to run in my 5.5" barrel SBR & HK pistol. From what I gather all 147gr. will be subsonic in this setup, but is it worth it to buy subsonic specific ammo? Is it really that much cleaner/quieter? I've looked at different options through freedom munitions, but reviews seem to be mixed on them. Anyone got some nuggets of wisdom to drop on me here?
