This 1911 slide is made by Rock Island Armory / Armscor. It is a Rock Standard full size 5″ slide for .45 ACP.

We have had these cut for RMSc optic cuts. This process deletes the rear dovetail cut. The slides were then bead blasted and finished with black nitride. As such, there are NO logos or writing on the slide.

    • Shield RMSc, RMS, RMSx, RMSw, AMS, SMSc, SMS 2.0

The optic cut sits .217″ below the top of the slide. The rear shelf from the original Novak cut sits .110″ above the base of the optic cut. Features front locating posts and cut to use 6-32 optic screws (sold separately).

Slide is cut with barrel bushing lug grooves for easy assembly with standard barrels.
