How Does The Installation Process Of A Red Dot Sight On A Glock Typically Work?

Installing a red dot sight on a Glock typically starts with selecting a compatible sight and ensuring the slide is properly prepared. Many Glock models require milling or a pre-cut slide to mount the optic. If the slide is not pre-cut, a gunsmith can machine it to fit the red dot.
