These types of thermoplastics tend to be easier on firearm finishes than injection-molded type holsters such as Fobus.
They can be wiped / rinsed out, too.
Keep in mind that a carry gun WILL get wear & tear on it. And that leather holsters can, will, and do retain "grit" and such which will enhance wear as well. (Plus, a leather holster CAN loosen up over time)
My Son is on the "Hunt" for a quality holster for His "New" to him Two-Tone CZ-75B.
His concerns are for safety+security, but most of all, kind to the PolyCote finish of the CZ.
