Recently just did a 25 cent trigger job on my 30. For people who don't know what that is, it's where you buff all your contact points on your internals. This made a huge difference. But does anyone know the actual poundage difference when u do this?
@Jelder The only way to know with any accuracy is to check yur own work with a trigger pull gage. Each one is different.
My G26, with 3.5# connector installed and nothing else, no polishing or anything, the measured trigger pull is 4 pounds 7.1 ounces (that's less than 4.5 pounds), measured with a Lyman trigger pull gage. She has had I would imagine over 10,000 rounds thru her. The average pull weight (meaning I measure 5 times, add the measurements up, and then divide by 5) is 4 pounds 4 ounces. Unless you measure it yourself, you will never know. Perhaps you can take it to a local gunsmith and ask him to measure it for you? Shouldn't cost anything to do this. Variations in manufacture and assembly, as well as level of wear, can have a large effect on measured trigger pull weight, so it is best to have your Glock measured and not to rely on any one else's measurement. Not very helpful, I know, sorry....
Oh and i used Mothers polish. 8oz bottle for 5 bucks even at walmart. All glocks triggers are different but the average i would say would be 5 pounds, IMO.
When I do revolver trigger jobs, I first use Flitz and a dremel, then follow-up with red jeweler's rouge with Dremel and very very light pressure.
