My grips are semi-wrap around style too. The top of the left side of the new grips just barely touched the bottom of the slide and the front of the left side would contact the safety selector when the selector was moved to the rear. This required about ten minutes of sanding and test fitting and sanding again to get the slide and the safety selector to operate freely. After that the grips fit fine. I took the pistol to the range and everything functioned as it should. I am very happy with the new grips.
