The Clip Draw is attached with a double sided kind of tape.. it's very secure and works well... In his application, he put it on the frame which might be a good idea. When I had mine, I put it on the slide, and that worked well until I got a IWB holster and took it off.. I made the mistake of using my pocket knife to lift that 3M tape off.. and now I have a nasty scratch to show for it.
