Can You Put A Red Dot On A Beretta 92fs (M9)? It doesn't look like it can, but there are ways...

The easiest way is to use a Dovetail rear sight adapter, and we recommend the Sight Mount Gunsight

Another way is to buy a Langdon Tactical 92FS optic ready slide.

So, Let's check it out...

[New] Langdon Tactical Elite 92FS Optic Ready Slide

Thanks to Langdon Tactical for finally making a low mount Beretta 92FS slide available to the market in 2020.

It was a difficult upgrade, but Ernest Langdon at LTT has figured it out!

LTT RDO is the official name and you can check them out on Langdon Tactical's website here.

Why we didn't see this upgrade before - The original 92FS has the firing pin block protrudes out of the top of the slide. The extractor is long, situated high on the slide, and, it’s basically impossible to install a red dot into the slide like a Glock.

What we like about the slide upgrade - Langdon Tactical trimmed the safety lever. In another word, they decided to sacrifice the rear sight dovetail to free up more real estate on top of the slide and incorporated an integral backup rear sight into the red dot's mounting plate.

  • The optic sits low compared to dovetail mount
  • No reliability compromise
  • 5 new redesigned parts:
  1. Firing pin & Firing pin block
  2. Extractor pin & Safety levers
  3. Safety plunger & additional red dot adapter plate.

Langdon milled out the slide as low as possible (0.14 inches), leaving just enough material above the extractor channel, then modified the extractor pin accordingly. And they re-engineered the firing pin and firing pin block to take up less space, so that they can function properly underneath the mounting plate.

This places the red dot as low as physically possible in the Beretta 92 slide. LTT measured the distance from the center of the bore to the center of an RMR’s window at 0.85 inches.

Sight Mount Gunsight Mount - 2nd Option

Beretta M9 Red Dot Sight Mount

The dovetail beretta 92fs red dot adapter mount replaces the rear iron sight without using the rail mount plate or milling the slide.

SightMount is a piece of Picatinny rail that replaces the rear sight assembly on the slide. The difference is that the middle rail cross-section is cut for three-dot sight sight picture acquisition.

But the optic sits too high on the slide.

Other Beretta 92FS Optic Mounting Plates - 3rd Option

The following options are dovetailed adapters that require no milling on the slide at all. All of them are fitted to go on top of the slide and it doesn't conflict with the trigger block.

Make sure to use some Loctite to secure it on the slide.

Rail Mounted Beretta 92 Scope Adapter

This might NOT work for all the Beretta M9 series handguns. It will for the railed framed version such as M9A1, 96A1, M9A3.

The rail-mounted sight adapter will make your M9 handgun look like a competition pistol.

This concept is pretty popular even for other striker-fired pistols.

It reduces g-force on the red dot sight, and it allows better dot tracking for a faster followup shot.

Beretta 92X RDO - 5th Option

Wrap Up!

The Beretta 92FS, 92X and M9A3 are not optic ready like some of the striker pistols on the market today.

The dovetail adapter is the cleanest and the cheapest way to set up an optic.

The NEW Langdon Tactical and 92X RDO have finally put the 92FS series pistol into the red dot game.

The LTT slide is highly recommended.
