If you follow the Talon instructions EXPLICITLY, you'll get good results.
I've got them on a .40 Shield, and a .380 BodyGuard. I like them. But I cleaned the grip frames BEFORE I even used the provided cleaner pad. And I carefully fitted them to frame, then followed by using a professional grade hair dryer to heat-set them to frame. (My youngest daughter, a hair-style professional, left a dryer at the house)...
If you stick them on a greasy frame, and don't heat-set them, expect them to peal off...
