Will not fit the SPG43 with RMS-C cut
The GGP RMR Cover Plate is custom milled from G10 composite to perfectly fit in the RMR cutout of GGP G19 or G17 slides when a Trijicon® RMR optic is not installed. Each cover plate includes two 1/8" screws for installation on GGP slides. These plates are made for GGP slides and will not fit other aftermarket slides.
Available in four colors: Black, Grey, Black/Grey, and Black/Coyote
****if your slide is cut for RMR ONLY the Black cover plates will be slightly too large and will require special fitment.
