I have a question for the experienced Glock people here.  I have two gen4 Glock 19s, and both have tough triggers.  They are supposed to be 5.5 lb and have the dot connectors.  I also have a G23 gen 4; also 5.5lb with dot connector, but the trigger is perfect.  Smooth take up, crisp breaking glass type drop.

All these were brand spanky  new from factory, no mods, and all bought over the last couple years, with the most recent just last month.  The newest was also the worst...gritty and rough feel in addition to the heavy trigger.  I bought a Ghost 3.5 connector and spring kit.  That solved the grittiness and might have lightened it up just a tad.  Intrigued that it didn't have a big effect, I swapped slides with the 23.  Wow....the G19 now had a very nice, lighter, crisp trigger and the 23 was now heavy.  So my conclusion is the striker.  The spring kit from Ghost included a safety plunger spring as well as a new striker spring in addition to the connector and trigger springs that "should have" eliminated those items.  I've put about 100 rounds through the newest on...and dry fired a LOT to see if it gets any liter, but it looks like it is striker related...  what you all think?

All pistols are dead reliable, btw, and all eject perfectly so far.  The other G19 has around 600 rounds or so... thentrigger on that one is smooth, but also heavy.  The 23 has 500 rounds or so... and would sure love to get the 19s to that pull weight.  And no, I don't have a trigger scale yet...


Thanks!

Check your safety plunger spring to make sure it's set in the plunger correctly in the 19. You can try swapping the firing pin w/spring between slides to confirm that's the issue.

Anecdotal, but in my personal experience, my gen 4 was gritty because of the little nipple on the newer gen 4 trigger bars. I swapped in a gen 3 trigger bar and the trigger has been smooth ever since. I also took the opportunity to polish the striker block because why not?

I've experienced the same thing.

I yanked the safety plunger completely... just to test of course.  Seemed to make no difference...  I wonder if the engagement is any difference on the striker with the gen3 trigger bar.   Not sure what to do next.

The nub would not do that in fact it makes the trigger pull more consistent pull after pull vs the Gen3.  The difference you probably experinced it the stamping of your trigger bar.  Not every bar is stamped equally.  Some have rough spots that give a gritty feel some are stamped cleaner giving a smoother trigger pull.

A well worn trigger bar Gen3 or 4 will have a better smoother pull than a new one.  I have tested all the different bars with a gauge and the nub causing poor trigger is a myth in fact in my testing I found that is made the pull much more consistent each pull with less fluctuations.. when the pistol starts getting dirty the nub acts as a guide making the trigger bar take a more consistent path each pull.

Take your fingernail and feel over all contact surfaces on the trigger bar.  Feel for roughness or sharp spots.  Also check the plastic channel liner for damage or crap built up in the firing pin channel.

Ok, following EdgeCrusher's recommendation in this post and another similar, I went over the trigger bar...lots of rough edges...in addition, the ceracoating made some tighter areas as well on the inside near the connector.  Figuring at worse case I'd end up having to spend $15 on a new trigger bar, I carefully filed the edges, following it with some emory cloth to finish it up.  both on the side at the contact with the connector, and also the sear contact where it contacts the striker.  While I was at it, I lightly filed off the ceracoating on the inside of the frame by the connector...i could feel the tightness by moving the trigger bar.  Afterword it was much smoother, just by taking id down to the frame at the "guides" or raised plastic.  I put it together and it is now almost identical to my 23, maybe just a smidgen heavier, which I'll chalk up to needing to shoot it a while.

Thanks all...a happy ending!  

PS:  Yes, I did go over everything after, for safety...all good.
