Quoting okie john: “Glocks are harder to shoot as well as some other pistols because the trigger pull is so long and heavy.”
Sorry, but this made me laugh, to myself. (Not that okie john is incorrect, but not all truths are universal.) A reason I have trouble with Glock triggers because the trigger stroke IS so very short and light, but, of course, with mechanical distractions thrown in, and the weapon sitting so low in my skinny hand, that my trigger finger tends to drag along the frame*. I would stand in a line, in the rain, for a Glock with a trigger pull like my S&W K/L-Frame and/or Ruger GP100 revolvers.
That is a winking smiley, but I am not kidding. With the panic-demic curtailing my live-fire training, my Glocks stay at home, while I carry my revolvers.
I never could shoot a Glock as well as a GP100, or K-/L-Frame S&W, because every shot I fired with Glocks made me a better DA revolver shooter. Every shot I fired with any firearm made me a better DA revolver shooter, it seems. I could shoot Glocks “well enough for government work,” and well enough to carry them during personal time, but I’ll never shoot a Glock as well as a good-fittin’ revolver.
Actually, coming from a 1911 background, I understand the desire for a lighter and shorter trigger pull, so okie john is correct, from that point of view. No Glock trigger will ever be as light and short as that in a 1911.
When I used Gen3 G22 duty pistols, from 2002 to 2004, I installed NY-1 trigger return spring modules, and the lighter Glock factory connectors, to smooth-out that trigger stroke, to some degree. That made a significant difference. When I returned to using Glock duty pistols, though the much-better-fit-for-me Gen4, in 2015, I left the springs and connectors as-is, as it was no longer kosher to change anything about our pistols’ trigger systems. (We owned our duty pistols, within guidelines.) Gen4 Glocks not only fit me better, but were found to have better-for-me triggers than Gen3.
*I finally learned a name for the cure; Boresight Solutions calls it a “glove bevel,” or something like that. I just might have something like this done.
