Colt
The Colt Mfg SP301329 1911 optic plate is a dedicated mounting solution that brings your classic Colt 1911 into the modern optics era. Built to accept Shield RMSc and Holosun 507k series red dot sights, this plate gives you a compact, low-profile way to run a proven 1911 platform with contemporary sight technology—ideal whether you're building a duty gun, a concealed-carry setup, or a versatile range rig.
This isn't a universal adapter. Colt engineered this plate specifically for their 1911 platform, so fitment and function are dialed in from the factory. The integrated Glock dovetail rear sight cut means you've got alignment reference built in, eliminating guesswork during installation and ensuring your backup sights and optic work together as intended.
If you run a Shield RMSc or a Holosun 507k—including the popular Holosun 507k X2—you already know the footprint. This plate bridges the gap between slide and optic, giving you a proven red dot mounting standard on a gun with deep roots and proven ergonomics. Whether you're an old-school 1911 shooter looking to upgrade your sight picture or building a modern carry gun with classic DNA, this plate gets the job done without compromise.
This plate is engineered for Colt 1911 models. Always verify fitment with your specific slide before ordering.
The SP301329 is designed for optics with the Shield RMSc or Holosun 507k footprint, including the Holosun 507k X2 and similar models in that series.
The plate includes an integrated Glock dovetail rear sight cut, but does not come with the sights themselves. You'll need to source and install compatible rear sights separately.
Yes. The low-profile design makes it well-suited for concealed-carry builds, though final fitment depends on your holster and carry setup.
