I have two shoulder holsters for the Walther PPK.

The first the best of the best made for the PPK, it is the Galco Executive. These have been discontinued and very difficult. I've never worn it, it came with my PPK when I purchased it a few years back. It is in like new condition with no visible wear. The last two of these I saw sell on eBay went for $300 and $400. I am asking $275 shipped for it.

The second is a Galco half harness shoulder rig with a SH3 holster with thumb break. It is in very good condition as well. I am asking $105 shipped for it.
