Gen4 19 vs 21 Trigger

    Hi everyone,

    I'm the happy owner of a Gen4 19 and Gen4 21. The 19 went through the well-known ejection-to-the-head problems, getting an updated RSA at the gun shop, and finally going back to Smyrna for a new ejector. It's been absolutely perfect since then with about 1,000 flawless rounds.

    Except for the trigger. The trigger on the 19 is awful - lots of creep and stack, long takeup, tight, gummy break. I've had a gunsmith check it, tried the "-" connector, the NY1 spring, a lightened firing pin safety spring, and have polished everything mirror smooth. I even filed down the Gen4 trigger bar bump a little, and smoothed it out. None of that really did much. It's a little lighter and a little smoother but still awful.

    Then I brought home the 21 a few weeks ago and was shocked. The trigger in the 21 is amazing - extremely smooth, light and clean break, minimal takeup, fantastic reset. Honestly it's as good a trigger as many nice 1911s I've fired. It's bone stock and I'm not going to do anything to the gun except changing to Warren-Sevigny sights.

    I understand that quality control can cause big trigger differences in Glocks, but:

    1. Can anyone explain specifically why the 19 is SO BAD (even after all the work) while the 21 is SO GOOD? I hear from many people that the 21 trigger is outstanding - but why?

    2. Can anyone recommend a realistic way to make the 19 trigger as good as the 21 using stock parts only (I want to stay with stock parts)?

    Thank you very much.

    Welcome to Glock Talk.

    First thing: I assume you are lubricating both similarly with one drop of oil placed just under the connector hook.

    While not a Gen 4 19, I find the Gen 4 26 trigger to be superior to the Gen 4 21. The 26 is nice and crisp while the 21 seems more mushy.

    Thanks for everyone's comments. The Vanek Classic trigger looks good. I lubricate both guns the same way - wipe down all internals with Eezox, and add the drop of oil at the connector.

    I like the idea of putting the 19 back to stock and trying a Gen 3 trigger bar - might try it.

    Thanks again.

    I bought a Gen 4 21 in Dec. My blue label dealer had 100 21's in stock. I had him bring out 10 21's, and picked my 21 out after dry firing all 10.

    I'm going through the same thing.

    My 19's trigger is pretty bad. Same as you describe. I've filed off the bump on a spare trigger bar, didn't help. I really don't know how it could be so much worse than my 21.

    Of my new Gen4 Glocks, I find the 21 trigger to be pretty darn good, with just a little "mushy" to it on takeup - but the trigger on my 17 is a thing of beauty. Crisp as can be. Not quite as light as my very broken-in trigger on my 1990 G19 - but still the all around best of any stock Glock trigger I've yet experienced.

    I have 2 G26's Gen4 (I carry one and my girlfriend carries the other), 1 G27 Gen4 and a G30SF. None of them have a good trigger in comparison to a good single action, but the G30SF has the best trigger of the 4, while the other 3 feel pretty much identical to each other.

    Your G19 has a nice trigger for CCW. You'll never be accused of an AD.

    Stop looking at the grass on the other won't get there. Pick the one you like to shoot best, and use it often-- the more you shoot, the more you will learn to live with it. Best is the (-) connector with a 6 pound trigger spring, and reduced power striker plunger spring, and leave all other parts stock then be happy with what you have.

    Resign that every gun is different, and feels different (I own several 1911's, they all feel different, I also own several Glocks, and they are not identical either). Trying to turn one into another will just be an exercise in frustration

    Thanks for everyone's replies, much appreciated. I changed to a new Gen4 trigger bar with smooth trigger, a - connector, and a NY1 spring. I polished everything before installation. It's definitely smoothed out and has a nicer pull, but I agree with cciman that living with it is probably best at this point. I really do wish it were as good as the 21, though!
