Great target shooting reflex scope - Leupold DeltaPoint Reflex Sight Matte 3.5 MOA Dot

I mounted the 3.5 deltapoint on my performance center m&p c.o.r.e 9mm with the plate supplied by s&w. Installion was easy. I sighted in at ten yards firing about 125 rounds just to find a preference where I wanted the dot located and co witnessing with the iron sights. Once I was pleased I went to 25 yards. First three shots in the bull. I was very happy as a 62 year wearing progressive glasses now I thought I never would have done that again. The only issue is like others have stated is the rear sight is in the way of the locking screws. I plan to do as one other reviewer did, heat and bend the t5 wrench to do this. I did not use the supplied wrench to adjust the sight but bought a screwdriver set from lowes which had a t5 bit.
