For a knock around sub compact it's going to be hard to beat the Hellcat or 365. As far as replacement costs go, if you have one bought before the prices blew up consider what they're going for now. I'd say be happy and hold onto it. Personally a PRO sized gun is just too big for practical carry anyways. I'm also not a fan of carrying a "too nice" expensive shooter just because? If that little Hellcat is vetted at the range and you are adept with the DA trigger I say use it as it was designed to be used, comfortably concealed.
