The Overwatch Precision Defensive Applications Trigger (DAT) Kit is a flat-faced, direct drop-in replacement for your Glock Gen 1-4 OEM trigger. The shoe and safety are made from a solid body polymer which is attached to a polished OEM Glock trigger bar. This trigger is designed to provide the same great feel that Overwatch's aluminum triggers provide at a reduced cost for the budget minded shooter. As always, the flat-faced polymer DAT trigger will provide increased leverage to the shooter as well as a reduction of pre-travel by as much as 20% (depending on frame tolerances) without compromising firearm safety features, resulting in a clean, crisp break and reduced overtravel.NoteNot compatible with 19X or Gen 5 Glocks DISCLAIMER: This product is not manufactured, authorized, endorsed, or warranted by GLOCK.
