I realize you didn't get the answer you wanted, but you came here for info, and got it.
Unbunch your panties, and man up.
What "info" did I receive? I might have imparted some.
Yes, you did. I had never heard of this technique until your post.
But...your initial post refers to "lapping" which is normally done using an abrasive compound, which DOES cause all the issues the other guys were posting about. Your initial post also didn't give enough background info, such as a YouTube link to help us ignorant folks figure out what you were talking about. Therefore, "lapping" and "stock trigger", being a bad thing, was what everyone thought you were talking about.

As to the technique, if it works for you, great. I'm with rost495 on the dry-firing. While you may well smooth out some of the grittiness of that stock trigger with that process, you can gain invaluable muscle memory and training breathing, sight alignment, and proper trigger manipulation by dry-firing those 1,000 snaps that your technique will never attain.
Evidently, no one here had heard of the technique before, so, technically, you have received info, and probably more than you wanted.

The part that concerns me is by pulling up on the hammer, you're allowing the engagement surfaces to "roll" off each other. Even when lapping by conventional methods, it's important to keep the edges flat and to not change the angle. Maybe it feels better and will be fine or maybe it'll be unsafe in 500 rounds, only time will tell.
The part I have been trying to convey is good triggers are readily available and fairly reasonable. ALG makes a better standard trigger for around $40 and are proven but even they suck compared to a decent 2 stage trigger. I do understand trying to use what you've got. I have a new 6720 that I'm keeping irons on and would really like to keep the stock trigger but all my other guns have good triggers in them so I know I'll have to change it eventually.

I'll second the ALG triggers! For those not familiar with the company, it is actually owned and run by Bill Geissele's wife. Here's a video that explains the Geissele & ALG Defense companies;

That technique is pretty well known in the 1911 community (and others), and is known as boosting the trigger. It's not lapping as the OP said, it's burnishing. The technique varies depending on the firearm but the general idea is to load the hammer & sear surfaces together more than the normal spring tension, to burnish out minor imperfections or burrs. As you've guessed, it is somewhat controversial and often hotly debated.
In my experience, it can be a useful technique if done sparingly and only where needed. The improvement is small, and the effect (if successful) is just to smooth out the trigger pull. I've done it on GI AR15 triggers and it can help a little bit, but IMO it makes less improvement on an AR trigger than anything else I've tried it on. Mostly that's because stock AR triggers have so much more engagement surface than a lot of others.
If you try this, it is important to keep the contact surfaces oiled. Don't do it dry, that can cause galling.

Exactly...............it would likely help the most if the trigger was really rough in the 1st place.
The better the trigger is the less likely it will have any impact.
Probably less likely to damage an AR trigger for exactly the reasons you stated than it would a halfway decent, but not great, 1911 trigger.
Yup. It can definitely damage a 1911 trigger if overdone, but can improve a mediocre trigger if done right. I doubt you could overdo it on an AR by pulling the hammer with a string though; when I've done it on an AR I pry the hammer with a small punch or allen wrench. 3-10 trigger pulls with this method is plenty; more than 10 is usually overdoing it on most guns, although it depends how much pressure you put on the hammer.
Heard of this for sixguns. I pull them apart and smooth everything, change springs. For AR, I have just bought acceptable triggers, and accepted what they gave. Great triggers are nice, for most, any halfway decent triggef will suffice. If I ever decide on a super acvurate AR, then Gieselle would get my money.

The thing is, you don't really know how accurate your AR is until you put a good trigger in it.
