We will custom mount your Leupold Delta Point Pro red dot optic on the slide as described below, please check the Compatibility tab above to verify we can cut your slide model. We do a custom mount that requires milling of the slide to reduce the overall profile of the optic, bringing it down closer to the bore by lowering is 0.150". Unfortunately, due to the overall base height of this optic, it still sits too high for acceptable co-witnessing with typical suppressor height iron sights. The best solution we've found it to use the Leupold Delta Point Pro rear iron sight that is mounted to the rear of the optic and a Dawson Precision front sight with the appropriate height to cowitness through the optic. As such, we only offer this optic mounted such that the add on rear iron sight is roughly flush with the rear of the slide. We are careful not to alter the function or reliability of the internal workings of the slide.
