Best Glock FRT Triggers 2026: Forced Reset Kits Ranked
A forced reset trigger gives a Glock follow-up speed faster than a binary trigger while still firing one round per pull, but the Glock fire-control group is tighter and more generation-sensitive than an AR-15's, so fitment matters more than brand. This guide ranks the Glock FRTs that actually ship in 2026, with the exact generation each one fits, what Gen 5 owners have to swap, and where these triggers are legal so you buy the right kit for your frame and your state.
