Our Trijicon RMR cut is milled to a depth of .125" which includes front recoil posts and 6-32 mounting screws. 
 
If your iron sights are not compatible with the optic/optic cut we will not reinstall them. Incompatible sights will be shipped back with the slide. An example of an incompatible sight would be a sights that hangs over the front dovetail 1/16" of an inch. This amount of hang over will collide with the RMR. Please see our Super charger sights for a compatible lower 1/3 cowitness.
 
Dissasembly is not required. We do not charge for dissasembly/reassembly. If you inlcude aftermarket sights, we will install them for free upon reassembly.
 
Our cut does not work on the 42. 43. 43x. 48.  or 17L/41
 
Coating is not required, but highly recommended to prevent corrosion from developing underneath the optic. Please add the Cerakote option from our webstore to your cart if you would like us to coat your slide. If Cerakote is not added to your order, we will ship your slide back to you in a raw finish state as shown above.
