For those who want a pistol-mounted red dot that will fit a slide without a slide cut while still co-witnessing the front sight, Leupold now has you covered. 

Building on the company's Delta Point Pro's tradition, the new Delta Point Micro is a direct replacement for a factory rear sight on Glock and Smith & Wesson M&P series pistols. The versatile new sight is lightweight – hitting the scales at just 1.1 ounces – and uses a simple 3 MOA red dot with eight brightness settings and a tool-less battery compartment.

Best of all, this electronic ghost ring sight does not require a slide to be cut for optics or the use of mounting plates. 

“As our team designed the DeltaPoint Micro, they knew it needed to be three things: low profile, easy to use, and tough as nails,” said Tim Lesser, Vice President of Product Development for Leupold & Stevens Inc. “It delivers on all counts. No red dot on the market is more compact; its low height to bore replicates the same sight plane that iron-sight shooters are used to, allowing for intuitive target acquisition; and it delivers the legendarily rugged performance that Leupold consumers expect.”

While the DeltaPoint Micro's CR1632 battery has what Leupold bills as a 3.5-year constant runtime on a medium brightness setting, should it fail the optic continues to serve as its own backup sight.

“If the battery dies or you experience some sort of failure, the DeltaPoint Micro can be used like a ghost ring sight,” said John Snodgrass, Tactical Product Line Manager for Leupold & Stevens Inc. “By putting your front sight in the bottom third of the window and using the two milled holes on the back to align with the front sight, you’ll still be able to get on target fast, without adjusting grip or presentation."

Guaranteed for life with a lightweight aluminum housing and double Diamond Coat scratch-resistant lenses, the DeltaPoint Micro is made at Leupold's facility in Oregon.
