I have clipdraw clips on all of my Glocks (G19, G23, G32, G26 & G27). I also have the Universal Clip Draw on one of my Kahr PM-9s. If you clean the slide correctly, and clamp the mounting plate to the slide, and kept it warm for about 24 hours it stays on, even after firing 124 grain +P rounds. I have about 300 rounds fired with my PM-9 with the Clip Draw attached. It's still holding tight. All of my Clip Draws work very well, BUT you must be VERY aware of the uncovered trigger! If one is not an experienced handgun user, and does not have their finger straight and away from the trigger on EVERY draw, then they should not carry a loaded gun without a holster that covers the trigger. It's like anything else in life. Clips on handguns are not for everyone or for every situation, but they do have their place in the life of a responsible handgun user. P.S. I also have a number of good holsters for all of my pistols, and use them when needed.
