Shoulder Holsters; Why so expensive?

I know shoulder holsters are kind of niche. But I've been wanting one recently for a Beretta Bobcat. It's more of a cool thing for me rather than practical. I've recently watched Dr No, again. I know Bond was forced to give up his Beretta 950 for the legendary Walther PPK. But a Beretta is what I have, although not the Jetfire.

What I would like is something like what Bond had. Although his didn't have provision for spare magazines or silencer. Kinda odd that. A small can/pillbox can go into a pocket. Having spare mag pouches on the right side (I'm right handed) would be nice. Also, I don't want it flopping around. I would also like a retention strap on the holster itself and for it to be a drop down type so I'm not flagging everyone behind me.

Would anyone care to recommend a suitable shoulder holster that does not cost a small fortune? For reference, 1000 rounds of Aguila Interceptor, if you can find it, is a small fortune! LOL.

Thanks.

Check out these holsters from Barsony. I've used their leather IWB holsters for many years and I have been looking at a leather shoulder holster for riding my motorcycle. They aren't so expensive they'll break the bank if you don't like them and their leather is pretty good quality.

Thanks for the recommendation. They seem to lump the Jetfire through Tomcat in the same category. Mind you, the PPK is somewhat larger than the Jetfire. The checkboxes are mostly ticked except for vertical rather than horizontal. But who here can claim not to have a box, drawer, or trashcan not filled with unsatisfactory holsters?
