I have a G22 Gen4 that I use as a duty weapon. I have other glocks, all gen3 models, and the trigger on the G22 is noticeably more stiff than any of my other glocks. I would like to change the trigger or at least alter it in order to make it better. Any suggestions on what some options are that would still keep it legal as a LEO gun? And has anybody else noticed that their gen4 glocks have slightly stiffer triggers?
