Sub-Sonic 9mm & 300AAC Ammo Recommendations

[RifleGuy]

147 gr will 99 times out of 100 be subsonic.
220 gr 300 BLK will be as well. Most 200 gr, too.
Almost any 45 ACP will be subsonic regardless of gr (know you didn't ask, just throwing that out there).

You are probably going to need a Nielson device for that Hybrid 46 to work on any pistol. Would highly recommend calling SilencerCo and finding out. If not, you've got yourself a bolt-action pistol.

This was so with my Glocks & my Hybrid. Small expense, works like a charm.
