You can't take it out. I checked... LOL
You may have already gone this far, but if you haven't --
You can remove the retention mechanism by loosening (and removing) the hex-head on the outside top (front edge) of the holster. The hex screw is really tight. The whole retention unit comes out as a single piece -- and it's a very clever design. (It can, as easily as it came out, be reinstalled if you're unhappy with how the holster fits the gun, later.)
With that assembly removed, the gun is still reasonably secure in the holster, but a wee bit more loose -- but you can tighten it up using the two screws on the lower bottom front of the holster to make the gun secure. That done, it won't easily drop out if the holster is turned upside down.
You'll have to try it to see if it keeps the gun secure enough for you...
I've played with the holster a little, and I don't, yet, find it an easy holster to use. I can't get a clean presentation, yet. I have other holsters, including a pancake USP 40 holster, that work much better for me. I'll keep working with it, as it may just be me -- not figuring the best way to make things happen. (I may have to loosen up those screws I tightened to make the gun more secure...)
For the money, it's a great backup holster -- but I wouldn't presently consider using it for concealed carry, at least as it's currently configured and adjusted (which may not be optimal.)
