This is another product that released in 2020. It flew under my radar so I’m sure it flew under your radar as well; I even missed it while looking at their website!
Last year Langdon Tactical announced that they had solved one of the most difficult problems for the Beretta 92 series; mounting an optic without losing your rear sight, while being more stable than a dovetail mount. In order to accomplish this, Langdon Tactical did have to machine some proprietary parts to accommodate how the firing pin safety functions.
Immediately after, a lot of people were wanting to just buy an additional optics ready slide versus milling their factory one; and subsequently voiding the warranty. To accommodate the requests, Langdon Tactical added optics ready slides to their shop! Available in Black, FDE, OD Green, and Sniper Gray for both full size and compact Beretta 92s.
On their website it’s listed that the slides will work with any 92FS or later models with the only two exceptions being the 92A1 and the 92S; I used to have a 92A1 and that isn’t a big surprise to me and I still don’t know why they made it while producing the M9A1.
You can find the slides here.
