I wear a crossbreed ankle holster while inside the house on most occasions. For quiet a while, I was holstering my Version 1 Sheild 9mm. Recently I felt is was a bit heavy, so I switched to holstering my Sig P365. It fits, but if they offered a smaller size (which they might), it would be preferable. The Sig P365 is about the same size as the Hellcat, so I would they're comparable, as not being too heavy, and comfortable. The Shield wasn't bad, just a bit heavier than the P365 and my Hellcat that I wear IWB for my EDC.
