The G-Plate, designed for Glock(R) 19 (and other Glock pistols that share the Glock rear sight dovetail) and the Sig(R) ROMEO X optic. Originally developed at the request of a user group, this innovative plate allows shooters to mount a Sig ROMEO X on a Glock 19 slide without any slide modification, making it ideal for low-visibility and discreet carry applications. The G-Plate replaces your factory rear sight and mounts directly in the Glock dovetail, providing a secure, low-profile optic solution. The ROMEO X features an integrated rear backup sight, and the G-Plate adds a matching front sight post to retain fixed or backup sight capability if needed. Precision machined from billet 17-4 stainless steel and finished with FNC (Nitride) for maximum corrosion resistance, the G-Plate is built to last. It includes a Nylok-patched stainless steel set screw for added security. Compatible with Glock 19 and other Glock slides using a standard dovetail cut Machined from billet 17-4 stainless steel FNC (Nitride) finish for extreme durability Weighs only 24 grams Includes Nylok-patched stainless steel set screw Proudly Made in the USA
