Does anyone know of anywhere to get replacement basepads, with pinky extensions, for a 9mm, 320 sub compact?

I was thinking about ordering one of these to try it out:

They may be a new product cataloged but not in the
wild.

Let me know if they are in stock. Several others have them listed as "out of stock".

When I had my 320sc I used X-Grip Magazine Adapters on P320 compact mags. This provided more rounds and a bit more grip.

Thanks for the links!
Big Sky shows stock, the other place, no.
I was going to order 3, which is about $24, but, Big Sky wants another $15 to ship.
I sent them an email asking them if they could maybe ship cheaper.
I have a compact grip I could use, but, the sub-compact is shorter, and with a pinky extension won't make it print any more than a flat basepad. I use pinky extensions on my 1.0, M&P compact, and my Kimber Solo, and my Bodyguard .380.

I used some Glock 43 extensions. Sanded the bottom and glued them on wiht Super Glue.

Once I knew who actually makes them, and the part number, it seems that a LOT of places list them, but, they are new enough that the only the one place shows stock.
I can wait for a little while.
Surprisingly, Amazon doesn't even show them.

I don't get pinky extensions. You're making the grip longer without adding capacity. Why not just get the Compact if you're gonna make it Compact sized?

If you’re carrying concealed, it is the bottom, rear of the grip that has the most tendency to print. I believe Ed Brown was one of the first to address that issue with his Kobra Carry, which is an outstanding pistol, but, for me I thought it was a little heavy, and even though I’ve put thousands of rounds down range with 1911s and 2011s, shooting IDPA, USPSA, and 3gun, I want a striker fired gun for carry/personal protection. IF I ever HAVE to use one, I want it simple as possible. Just draw, aim, and pull the trigger. I will probably end up with either the compact, or, full size upper on the sub compact lower. I’ve found that the little guns not only are harder to shoot accurately, with the shorter uppers, are also harder to keep them where you want them to be, if INSIDE the waistband
