First thing I would be is check to see if the grip screws are dragging on the magazine.
If you look up the magazine well with a flashlight you should see the end of your grip bushing not the grip screw sticking into this area. At the same time you can see if there are any marks on the bushings to see if they are dragging on the magazine.
Something is dragging to cause the magazine to not drop free from a 1911.

It looks like its getting released partially and then getting stuck in the vid. I'm not a 1911 expert, but i'm going to guess it might be the trigger bow dragging on your magazine? Have you fully disassembled the gun, cleaned and lubed it?

Try a simple thing first - - -

Measure the mouth of the magazine - I had one recently get bent - it wouldn't fall free for anything - - it may be the dang magazines are just a tad wide for your mag well.

Try another magazine or measure against one that falls free - - if you don't have another brand - borrow one from another shooter and see if it falls free.

This solved it!

Thanks!
