Hi Frederick and welcome to the Buds Community. Yes, With only the barrel and magazine different, the Shield Plus in 30 Super Carry has the same dimensions as the 9 mm Shield Plus. Any Shield Plus Holster will work. I highly recommend Alien Gear and you have a wide selection depending on the carry method you chose : https://aliengearholsters.com/holsters/sw-mp-shield-plus.html -------- Cheers and stay safe!

Fredrick, yes sir, the 30 super carry is almost identical in shape as the shield plus 9mm. Most holsters are advertised for both. I'd recommend a holster from crossbreedholsters.com or aliengearholsters.com . Just Google the website and type in shield plus 9mm. Both companies make fantastic holsters but my first choice would be crossbreed. Hope this help and you're very welcome.
