    Picked up my latest Glock yesterday, a blue label Gen 5 19 with stock sights. I noticed the front sight was taller than the usual OEM sight, so I did a little research.

    Glock now calls the Gen 5 polymer sights, GLOCK Modified Sights and uses "GMS" in the Parts Order Form (Certified Armorers)

    There are now two polymer front sights available. All models, including the 42 and 43, use to use a single polymer front sight in the past. Now there is a 4.1 mm and 4.9 mm tall front sight, where the 4.9 mm is the GMS version. Glock has a web page describing the differences

    https://eu.glock.com/en/products/glock-options/polymer_sights

    On a side note, when viewing that page you will see nomenclature such as (1), (2), (3), and (4). That is referencing the numbered photos in the picture slide.

    Personally I prefer the original 6.5 mm rear (182) and 4.1 mm front sights (SP06956) and have ordered those from midwestgunworks.com. Add an Extended Magazine Catch (8794) and 47021 ejector from a 47208 Trigger Mechanism Housing and my new Gen 5 19 will be just the way I want it and still "stock" for GSSF matches.

    someone else posted that GMS = "marksman" thus designating the G5 as a "sporting" pistol thus sidestepping the import rules and allowing the smooth trigger shoe. Or something to that effect.
