Gen 5 Glocks take our forced reset trigger kit, with one required change that trips a lot of first-time installs. This page covers the Gen 5 fitment across the 17, 19, 19X, 34, 45 and more.
Yes — Gen 5, Gen V and Gen 6 pistols all take the billet flat-face FRT shoe and reset. The kit fits the Gen 5 Glock 17, 19, 19X, 26, 34, 45 and the rest of the double-stack Gen 5 line. It does not fit the .22 LR Glock 44 or the slimline 43/43X/48.
Every Gen 5 / Gen V / Gen 6 Glock ships with a factory ambidextrous slide release. It interferes with the FRT trigger bar, so you must replace it with a Gen 4 slide release before the kit will run. This is the single most common reason a Gen 5 install feels wrong.
The installation guide walks the whole process.
The Gen 5 factory slide release is ambidextrous and its left-side lever contacts the FRT trigger bar. A Gen 4 (non-ambi) slide release clears it, so the trigger resets correctly.
No. The 43, 43X and 48 are slimline single-stack pistols with a different trigger mechanism. This kit is for the double-stack Gen 1–6 frames.
