It will probably be hard to find a holster that's not going to cause some degree of wear on your gun. It didn't take but a few months of EDC to notice holster wear to mine. I'm guessing a quality leather holster would be less abrasive than a kydex. Galco and desantis make some quality holsters for a reasonable price, you might check them out. I prefer Crossbreeds super tuck for EDC, very comfortable and easily conceals. With a full size glock like the G22 I'm not exactly sure what options are out there, I've never tried carrying a large frame.
