Optic Ready
A handgun sold with a slide cut and adapter plates ready to mount a red-dot optic.
An optic ready pistol comes with a slide cut from the factory plus a set of mounting plates that adapt the cut to common red-dot footprints. The plate covering the cut is called the blanking plate — it’s installed when no optic is mounted. Optic-ready has become standard on duty and defensive pistols since the late 2010s as red dots displaced iron sights for serious carry.
