Scott, I don't blame you at all for this, but I purchased my Octane 9 from you, and it has been one of the worst suppressors I've owned. On my glocks with subsonic 147 or 158gr it is not hearing safe because the port pop is extremely loud, leaving your ears ringing. I can remove the octane and throw an osprey 9 on and with the same ammo it's completely hearing safe.
On my MP5K-N which has a B&T navy barrel (so 100% HK spec 3 lug), the original Silencerco 3 lug mount I received was extremely loose, and caused an end cap strike. The replacement they sent me was no better, resulting in another end cap strike. Meanwhile my friend's old SWR 9mm can works perfectly on my 3 lug in full-auto.
The Octane is long and has a lot of back pressure. I do not recommend it.
