Requires a THREADED BARREL in 1/2-28. Most of these pistols do not ship with one — check your barrel before buying. Compatibility (read 2026-09-21): "Glock 17/19/26/45/34/19x (including the MOS models of) with 1/2-28 Barrels and must be GEN 2-6 Glocks, Ruger RXM, Shadow Systems MR - DR series." The title agrees: Gen 2-6. A highlight that says all generations is not the spec line. Catalogue cards exist for Gen 4, 5, and 6 of these models, not for Gen 2 or Gen 3 as their own rows, and not for a Gen 1-4 band. The 47 is not named. Zev OZ9, Lone Wolf Timberwolf and Dusk, Polymer 80, and "most other Glock clones" are not catalogue cards. Not compatible with SilencerCo, Bar-Sto, KKM, or EFK.
