.I believe I have found the holster that formed the base for the one used for K's blaster.
Just like Deckard's holster, it was originally made by Safariland, specifically their Model 1090 Gun Quick holster:

The 'Gun Quick' name was trademarked by it's designer John Bianchi in 1993 and the design was patented in 1995 by Safariland:

It looks like it was available from around the mid to late 90s at least - the oldest catalogue I've managed to find online is 2006 and it's in there. The big problem is that it looks like it was discontinued in 2016 (the last year it appears in Safariland's catalogue was 2015, though it was still in the 2016 price list).
The main modifications appear to be the swapping of lthe leather parts of the shoulder strap for synthetic material (as there's no leather in 2049). The side plates are separate pieces that are adjustable for different pistols, so they may have been replaced with custom-made plates to fit the blaster.
It looks like the silver sprung loop on the rear of the holster holds the gun in place under the the curved top of the backstrap and rolls up and over the slide as you draw it (pulling the gun down and forwards out of the holster), The spring loop can be seen in some shots of the film where K isn't wearing his coat but I can't see it in the pictures of the gun and holster from the WIRED article or SDCC displays. My guess is that it was getting hung up on the blaster when trying to draw it (as it doesn't have a smooth curved top on the grip backstrap) so an 'action' version of the holster may have been made without the spring loop.
Now I just need to id what material they have used to replace the leather strap.
