I just picked up a pair of Bravo Concealment holsters on their BOGO sale. Sold as Gen 5's, the molding looks like Gen 4 to me? They fit the G45 just fine.
I was afraid of the injection molded looking new version, for fear of it being Fobus like. It seems to be fine though, the gun clicks right into it. I got both holsters cut for MOS, should I decide to go that route in the future.
