Glock trigger pull harder and harder while dryfiring

[pinne65]

I recently took my G20 G3/SF apart and did the 25C trigger job. I.e. polished all the trigger metal parts.

The first couple of times dry-firing it the pull feels much better, (smoother).

But if I keep on dry-firing the pull requires more and more force until it gets almost impossible to pull the trigger. It's still smoother than it was before the polishing.

If I take the frame apart and re-assemble again the pull goes back to being normal again but degrades to require more and more force.

Any 2 cents welcome!

How did you do the polishing? I'm curious if you took too much material off at a critical point such as on the connector or trigger bar.

Any chance you have polishing compound inside the pivot points? You might need to do a full strip and clean everything very well.

Have you done this before? If you take them apart, take some pictures.

Hi pinne65,
I would do as Speedtriple stated Full Strip Clean relube. Put back together and try it again. If that don't work Email me if you like. I Curious if you took to much metal off as DAPSRT stated. I have parts here at the house we could try exchange them as a test.

I used a Dremel w polishing felt attachment and Flitz polishing compound. Just enough to get a shiny surface on the metal parts in the trigger group. I don't think I took much metal off. Could some part have gotten too slick?

This is the first time I do this. There were some pretty good instructions on how to dis/reassemble the frame on by this guy youtube:Reassembly of a stripped Glock pistol (PART 1) - YouTube. (Well, at least they looked good to me)

Some pics:




I just put it back together again. The trigger really feels nice. But probably won't last. I'm going to dismantle it again and do super clean and re-lube it.

Thanks everybody for your input!

Make sure the spring above the disconnector (trigger spring) is connected right.... sounds like something is binding up and or out of alignment. I have done the 25 cent job on both my Glocks and never had this problem. I would take everything apart, inspect all the parts and put it back together and if you need to, just look up some vids you YouTube.

 

[pinne65]

Ok,

It seems like a real thorough clean and re-lube did it. It's working again!

I had this exact problem once - the trigger return spring had been misaligned and caused a very akward trigger feel like what you explain. Stripped it, saw the issue, corrected it and all is well.

 

[pinne65]

That's interesting. How was the spring misaligned? Did you take off and put it back wrong? When I took the trigger bar off I had to force the spring backwards to 10 a clock and it moves freely. When reassembling I again forced the string forwards to 2 a clock from where it moves freely.
