I must have really weird factory guns with unaltered internals.
What Glocks are you shooting that have that much travel after the trigger breaks? Im sitting here as I type with a box stock 17 and 26, and the triggers on both stop as it breaks (I just tried a couple more, and they all seem to be the same). Just like the stock Colt Commander I have here comparing them. The resets on both are very similar as well, with the 1911's being just a tad shorter, but nothing really different.
Im also dryfiring a stock S&W Model 19 and a Model 10 in both DA and SA and either way, see no discernable difference or any travel after the trigger trips.
I think most of the manufacturers have done a pretty good job of providing reasonable factory triggers and shootable guns as they come from the box. Aftermarket stuff is BIG money and I think their marketing does a great job at working on insecurities, and sucking $$$ out of your wallet, more than it does anything else.
Personally, I think if you put all the money spent on all the "upgrades" into ammo and range time, and take advantage of as much free dryfire time as you can, youll come out way ahead on the other side, and will also be a better, all around shooter, and with pretty much anything you pick up.
At least for me, that has been the case. Keeping your "shooting muscle tone" in good shape too is something else that absolutely applies here and needs to be done, and is something a lot of people dont give a thought to.
