Not sure about those exact models but I do know that buds has the p365 SAS (Sig antisnag system) available for $638.

Then They have the sig p320 m17 ( this is the sidearm that was recently selected as the new pistol for the us military)for $670

Both of these pistols would serve you well, if those dont work for you l, you can always hit the "notify me when available" button. Have a good day stay safe

I would search the internet, and go to small private gun shops.

check with the major auction sites like G(un)B(broker) and G(uns)A(merica) Remove ()

Good luck with that ... small self defense size 9mm are about the hottest things on the market today. Even if you can find one, good luck finding ammo. They will be back in stock at some point but right now everything is getting hard to find.

Gary, demand is still high and supply low. I would check on large gun and accessory sites like (6)un (8)roker, Armslist etc as discontinued and hard to find firearms and accessories show up for sale by private individuals and small shops. Just replace (6) & (8) with G & B. I also use WIKIARMS to find real-time online firearm inventory : wikiarms.com/
