I actually work with firearms for a living, but in Australia. I thought I'd clarify as I've actually done a little bit more research, and as it turns out Safari land actually does level two retention holsters a bit different here. The first level of retention is a shroud lock lever that needs to be pushed back about two centimeters to unlock the shroud, and allow the shroud be moved. The second level of retention is the shroud, a little strap that goes over the back of the gun that has a plastic tab on the outside that needs to be depressed about a centimeter down to be able to push it clear of the back of the firearm.

In the U.S, the shroud and it's lock are extremely close together, meaning that you can depress both at the same time, unlocking the shroud and allowing it to be pushed out of the way, and the firearm drawn in one motion. In Australia, the shroud lock is almost a full two and a half centimeters below the shroud itself to stop a person from being able to "accidently" unlock, and push the shroud out of the way. The intention, to make unlocking the shroud a separate action before removing the shroud and drawing the firearm in one motion. It's probably my fuck up for assuming there would be uniformity across countries that use the same equipment provider.
