[Ambi decocker is the Omega. It means the decocker is on both sides. The original P01 doesn’t have a ambi decocker
Yeah.. but this shouldn't be a problem. Other's side lever will fit the holster, because there's always space. Holsters are mostly made as equal left and right sides of the pistol. So once you have room for decocker/safety on one side, it's also available on the other side.
