eBay always has some "decent" shoulder holsters for the 92 platform. And there going to be reasonably priced, But the are probably going to be nylon.
Cheaper than dirt has a pretty nice one , made by Tuxedo , looks to be pretty solid and has the option of carrying extra mags. Ill post the link for you to check it out.
