Osprey 45 or TiRant 45 like everyone has said. But since 10mm is a round known for high velocity it kind of defeats the purpose to try and suppress it.
The latest BCM Gunfighter CH also have some "gas busting" abilities. That said, I'm guessing most of the gas is coming out of the ejection port for you... Sounds like you came up with a good fix that also saves you from chasing brass.
