I think Guns and Gear & On Target Training, LLC misnamed his video in this instance. He calls it “Mastering the Glock trigger,” but mastering trigger reset is an essential pistol shooting skill that applies across a wide range of pistols, not just the Glocks shown the video.
Now, is Glock pistol reset more positive in both tactile and auditory senses than some other pistols? Yes.
That allowed, the basic premise of what he’s teaching works on many semi-automatic pistols, and it’s worth sitting through the relatively lengthy 14:20 video to soak it all in.
