I have shot about 4 boxes of 50 with my Commander Carry 45 and I noticed the grips seemed to be slipping on me. Well I am glad I checked the screws because one was very loose. It was so loose the star point on my screwdriver set was just spinning around and I thought it didn't fit it correctly. Well now I tightened all four screws as two others were loose, it should feel better. I have been told the screws should be checked regularily because of the powerful caliber might loosen them at times. Maybe some LockTite should be used or will that mess with the magazine slamming into the pistol? I guess it depends how much I apply to the screws?
