Can for 9mm/45/300 BO

[HfdSARG]

Very poor as in when compared to a properly sized suppressor. Shooting a 9mm out of a .45 can. That introduces a lot of inefficiency by shearing off less gas. Thus it is going to be louder.

Rugged obsidian 9 metered at 121.4 decibles. Obsidian 45 shooting 9mm 123.7 decibels with a 45 endcap. Put a 9mm endcap you will drop another 1 decibel according to rugged. I hardly think 1.3 decibels is worthy of a very poor performance rating. Some dedicated 9mm suppressors don't claim numbers that low. Tone should play into the equation. The rugged has a very nice tone compared to some 9mm cans that i own or have shot.
