Just added a pair I had previously ordered to my P-07. It fits snugly in the dovetail in both the front and the rear. I am not sure I am going to stick with them because I don't think the plastic will stand up to creative slide racking. In any case, there are no holes for set screws and I am not sure if Locktite will secure the plastic to the metal. Anyone know if they are just supposed to be tensioned in there or if there is an alternative method to secure the sights, especially the rears. Thanks for any help.
