I have a T-100 and purchased and installed the CZ75 compact grips from Thailand. They were the ones with the finger indents on the left grip and checkered right. The checkering etc is fine. Fit was snap in except the right grip screw hole which has to be elongated slightly inward. Easy enough. After shooting several hundred trouble free rounds I wanted to reshape the right grip where the finger goes to the trigger and did so with sandpaper. Much nicer for my hand, so much so I pulled them both and made both a bit slimmer and took even more off on trigger finger area. My accuracy improved simply because I had a better grip. The stock ones are like a cheap plastic Fisher Price toy toolbox rasp. I like wood, the feel and look...but that is very subjective. How did I restore the finish after sanding? Ah...just like they do in Thailand for handmade wood stuff. Kiwi cordovan paste shoe polish. Darkness ends up however you prefer, durable...I have stuff from there 43 years old. It ends up with a satin finish. Yes, it does seem Rube Goodberg...I can live with the stigma. Mine arrived in less than two weeks, free shipping, well packaged.
