I prefer the Delrin grips on the compact 45s: CS45, 4513, 4516, and 457. I've taken the Hogue grips off the ones that came with them. I have an ongoing project to convert 4513TSW grips, the ones with the "step" on the bottom, to fit the CS. Not something I'd recommend (it's a gold-plate PITA,) but I have plenty of time for stuff like this.
