Finding there isn't a lot out there specifically for them but have heard they are compatible with other compact auto's. Is there truth to that rumor? If so, which ones are they compatible with?

Thanks!

I've had good luck using Kirkpatrick leather. They make it to order but with better turn around times than they state.

I received a High Noon IWB Holster when I traded for my 99c. Great holster.

Try the Blackhawk CQC Serpa holster, it comes with a belt and paddle hook ups and have adjustable 3 position connections, reasonable priced, and great if you want carry concealed. I use mine all the time on SW99 and it is quite comfortable.

The S&W 99c is basically a Walther P99c with a S&W slide on it.
When I had my P99c I ordered a bunch of Mags for a S&W 99c because they were MUCH cheaper.
I think you'll find most holsters for a P99c will fit the S&W 99c.

Crossbreed Supertuck Deluxe works fine for me.
