I don't know why Sticky is a brand you don't like, but I use something similar for my backup North American .380 Guardian. Grov-Tec makes several sizes for pocket pistols; mine is a #2. It has a non-slip band around the middle, as shown. I am of the strict belief that 2 is 1, and one is none.

Addendum: The Hogue grip you see here was trimmed to fit this mouse gun perfectly; it was the closest fit I could find in the store. Flush-fit hammer, DAO action, the tiny scratches on the polished slide testify to its regular use over the last 25 years.
