David,
The police holsters usually have a different style of closure strap design. I think the holster is of the military style but if it has no markings, it would be a commercial holster for civilan use.
Here is a worn police style holster on eBay. You can see the difference in the closure strap design on this example.

BTW...sometimes if you post the State location and name of gun shop (as shown in the photos) openly in a posting, you might find some fellows that "lurk" on the forums may run down and beat you to the purchase...sly old dogs that some may be...
Present company excluded of course...well in this case you were "safe" as the gun you posted was not a Swiss Luger...so I was not tempted to call the shop with my CC info.
