Have it milled, or buy an aftermarket slide. Ignore the naysayers. Red dots on pistols are awesome, perfect or crappy vision. It takes time to adjust and train yourself. But it can be done by dry fire and retraining your brain. With a red dot, focus on your target not the dot. Bring the dot into your field of vision. Your target should be clear and the dot fuzzy. The presentation is the toughest part. I talked a lot of shit about dots on pistols when they first came around. I reluctantly adapted out of boredom and something to play with at the range. The dot quickly got rotated onto my carry gun.
I will say it’s harder to zero a dot on a pistol compared to a dot on a rifle.
