Not really, shoot it, clean it, repeat. Once that copper has worn in some, and you’ve shot and cleaned the gun a few times, that grittiness should be better. Polishing that is part of the 25 cent trigger job. That will help too, if you want to do it that is.

I had a really what I thought was gritty feeling trigger in my gen4 26, I have currently 6 glocks 2 are gen4 and have had a bunch of others over the years.

So my new 26 trigger was driving me crazy, so I tore it all apart and did the 25 cent trigger job including the connector and striker lug, and slapped it all together and it still felt like crap.

Next up was to swap the trigger out with a gen3...nothing, still felt like crap.

I called Johnny Glocks, and within 30 seconds he says 99.99% sure it’s the channel liner. 10 minuets later, new channel liner installed and viola trigger feels like it is supposed to!

Do a YouTube search for Glock channel liner and find the Johnny Glocks video on it and he will explain what the issue is

The feeling of grit can be several things including residue from shooting . In vetting new Glocks for carry and competition I do polish safety plungers with flitz and a dremel.

 

IMO, the safety plunger will cause the least amount of grit...prolly undetectable in many cases. Remember, it's a very small, weak spring that keeps it doing its job, so how much grit can it produce? Polishing it does, however, complete the entire trigger parts polish. The key spot (IMO, also) is where the trigger bar pushes on the plunger. A rough edge on the plunger or trigger bar, or both, can push the plunger in a way that it rides hard on one side of the plunger channel. That still won't produce much grit, but may be enough to feel. I personally sanded the top of the OEM plunger with 1500 wet dry paper just to round that 'edge' a little as well as the top finishing with 2000 wet dry. Also did the sides as well as the inside of the channel with the 2000. I use wet dry to remove the burrs which metal polish cannot always do, and when oiled, feels like rubbing two pieces of greasy glass together.

Replacing the plunger, as some do, is absolutely unnecessary...just clean up the OEM plunger.

 

Thanks very much for the great info folks! :cheers:

 

Probably not. The plunger has very little effect on trigger weight or feel. You can demonstrate this by taking it completely out of the gun.

The main reason for modifying the plunger is to allow it to remain functional with pre-travel removed. And that takes a lot more than polish.

 

Probably the correct answer.

I always lightly polish the plunger whenever I do the 25-cent trigger job, but "just because". I doubt that it has any real effect on anything, but I do subscribe to the cumulative effect belief - that every little tiny bit (may) help the overall effect.

Also, regarding the "1,000 round trigger job" being the same as the 25-cent one, it has been my experience, that they are not the same. After getting a well-used Glock, with a very gritty trigger (several times), I found that a detail-cleaning did not eliminate the grittiness. So, I did the 25-cent job, and the triggers smoothed noticeably. Proof positive, in my mind.

I believe what most say is the burrs that cause the grit will wear down over 1000 rds, and some may, but if you're lubing these parts, they will only wear so much before it's just rounded off burrs riding over each other. Still, that may be enough for the trigger to feel good, but why wait for the parts to 'come in'? Also, and critically thinking, here, are the bearing surfaces 'galling' to become smooth? At any rate, I agree...25 cent trigger job right out of the box if the trigger feels gritty. It's easy, fun, and gives you a reason to learn to take your gun apart and put back together.

 

Wouldn't bother.

Tried 2 side by side, blinded to which was in the gun, one polished and rounded, one stock new-- (changing nothing else, just the plungers)-- no change in how the trigger felt.

 

Friend gave me a Titanium Safety Plunger for my G17/4 LOVE my trigger with it!

 

I performed the $0.25 trigger job on my 19 without polishing the safety plunger (just skipped it). Put a few hundred rounds through it and then polished the safety plunger, did not notice a difference.

I performed the $.25 trigger job after putting several '000s rounds through my 19. I thought there was a noticeable smoothing of the trigger. Even if that change was just confirmation bias the $.25 trigger job was worth it because I learned a great deal about about the pistol.
