For my intended uses, I don't need 10mm for concealed carrying, it's meant for open carrying thus a subcompact or compact 10mm isn't something for me. Now, if I was living in Canada, the Rockies, Alaska, maybe northern New England, yeah, I could see this being a good combination of size for concealment and power for big 4 legged animals like moose and bear.
The sad reality for 10mm is that it's really built for a full size, long barrel pistol and those are NOT what sell in the US, so that's why nobody is coming out with polymer frame 10mm's even tho it's probably the fastest growing handgun cartridge.
