So I polished my trigger(s)...

[sc870]

So I've decided to polish my trigger components while I was deep cleaning my g22. It's seen around 3k rounds. Put everything back together and the pre-travel felt a whole lot smoother, although I can feel the plunger getting depressed. Ordered the grandmaster kit from tti and used everything but the striker spring. Felt even better.

Now here's my issue. I've recently picked up a g19 and did the same exact thing. The g19 has seen about 1k rounds. But the pre-travel is no where near as smooth. I used q tips and mothers polish for both guns.

Anyone have any ideas what's going on? Does the amount of rounds I put through it maybe make the difference. The g22 is a rtf model. Bought new old stock and the g19 was purchased this year brand new.

Certainly, use will burnish the parts which generally makes them run smoother. Try burnishing some tungsten disulphide or molybdenum disulfide powder or paste into the rubbing surfaces.

Theres a lot of variance in glock triggers from the factory ive noticed. I had a g21sf that had a light crisp trigger that was extremly smooth. Bought a g19 and it was extremely heavy and gritty. After i swapped the trigger for a smooth g17 trigger it got even worse. My trigger bar actually had a nasty burr on it where it contacts the safety plunger. Polishing wont remove any burrs/imperfections but some sandpaper or stones will.

Theres a good guide on another forum that details stoning your glock. Truing all the surface areas on the trigger, connector and plunger that contact each other will make a world of difference.

I think it might be something with the slide. I swapped trigger bars only and the entire trigger including the housing and ejector and my g22 is jus way smoother. First I thought it was the plunger, so I switched em with each other and my g22 is jus really smooth.

I've noticed something similar too. I have a 21SF and a 19, both Gen 3. The 21SF has a dead sexy trigger after a - connector and some polishing. I've dropped a - connector into the 19 as well as 2x the polishing and yet the trigger is not nearly as nice as on the 21.

This threads reminding me i shouldnt have sold my G21sf... lol

Hmm, im no gunsmith but im not sure how it could be the slide affecting the trigger pull... unless theres a burr in the safety plunger hole causing resistance. Couldnt hurt to check the striker chanel and end on the firing pin that contacts the cruciform for burrs.

Well I really thought it was the plunger since there were marks on it but I swapped it out with the g22 and the g22 is jus really nice.

Gen?, you don't say and that could be a big impact.

I find the Gen4 to be generally crappy compared to the Gen3. But I also find quite a variation from Glock to glock.

[sc870]

Both gen 3.

Q-tips and polish isn't really enough.

The plunger is depressed by that nub on the trigger bar and if you look at the edge you can see remnants from the stamping process. So you will want to hone the forward edge of that.

BUT. I think the pre-travel is the least important part of the trigger pull because once you learn how to ride the reset its moot.

The trailing edge of the crucifix has the same remnants from stamping. So spend some time their with a fine hone, or knife sharpening block, paying close attention not to change the angle of the edge.

Well I really thought it was the plunger since there were marks on it but I swapped it out with the g22 and the g22 is jus really nice.

If the marks are on the top of your plunger its probably a burr on the trigger bar(since you said the g22 trigger in the g19 made no differnece i doubt this is the cause) If its marked on the sides check the channel the plunger rides in on the slide for burrs. Since you also ran the g22 trigger in the 19 i would also rule out the cruciform.

If you don't want to take stones or sandpaper to your parts, maybe make a point to dry fire it a few thousands times then break it down and give it another polishing before shooting it again.

Btw here are the links to the glock stoning guide.

Cool. I wasn't really trying to eliminate the pretravel but jus make it smooth. The g22 is crazy awesome. May inspect a couple parts and dry fire it a bunch. Not comfortable taking sandpaper to it but of I have to I might. I remember when I did the apex kit on my shield it said to use something to smoothen out the part that rubs the plunger.

I used to worry. Then I watched this!

I don't think this will help much. Because I put the g19 trigger assembly in my g22 and it was fine. It felt the way I wanted it. I put the entire trigger assembly and the plunger from the g19 into my g22 and it was very nice.

Might have a burr on the trigger itself.
