The Leupold DeltaPoint Pro (DPP) is one of the few "all-rounder" red dot sights — pistol-mountable, shotgun-mountable, rifle-mountable — that's earned a strong reputation across all three platforms. The 2.5 MOA dot is the precision-friendly carry/duty option. Open emitter, motion-activated.
Specs:
DPP vs RMR: The DeltaPoint's lens is wider front-to-back than the RMR — slightly easier to find the dot quickly. The DPP also has motion-activated auto-on, which the RMR lacks. The RMR is more rugged in extended duty use; the DPP is preferred where speed-of-pickup matters.
Mounting: Most premium aftermarket slides ship with a DPP cut option. For Glock MOS pistols, our Nordic Components DPP plate mounts the DPP directly with backup sights included.
