Good mount! ? - ADE Advanced Optics Mini/Micro Reflex Dot Sight Mounting Plate for Colt 1911 Standard

Solid mount and fits a wide variety of mini red dot sights. Does not fit the bottom of older Optima 2000 pattern sights. dovetail was tight but was not hard to install on Springfield slide. I mounted this on a 9mm 1911 and have run probably 400 rounds through the gun with no problems. Mount is still firmly installed and sight has held Zero well.

I must revise rating. This base was mounted on a custom STI based gun with a Springfield slide and a compensated barrel chambered in 40 S&W and carrying a Redfield Accelerator sight weighing 1 oz. I didn't use the gun much over the summer. I recently took to a pin shoot. On the sixth round fired the screws stripped out of the base plate and the sight went flying back past my ear. I will be contacting the supplier for service.
