First, define what I like in a trigger pull:
First and foremost for me a short reset is mandatory, second a crisp striker release, and third a lower pull weight.
I looked hard and for long at the position of the trigger bar nose, when it's in the relax position, I.E. when rest above the connector raised step (sorry didn't have a name for that part).
I grinded some material in order to make the trigger bar nose reset in fire position earlier than before, basically you have to alter the top curve making it less round (please excuse me for my horrible engrish..).
I put a dremel upside down in a vise, with the grinding wheel perpendicular to the ground, marked the zone I wanted to grind with a felt marker, and proceeded to make a very light pass with sanding drum
BEWARE, have a strong light, and make very light contact with the grinding wheel, I learned this the hard way, I ruined a trigger bar grinding to the point that the striker was not released by the nose, with another trigger bar.
The procedure I took was the following:
-mark the zone of nose that is above connector angled step with a felt marker, fine tip.
-put the nose in contact with the grinding wheel, do a light pass trying to alter the curve in order to remove material from the point you marked. Try to do the pass in order to preserve the curve, don't do a radical angle, otherwise trigger pull increase.
-above all, A LIGHT PASS.
-reassemble, don't pay attention to the gritty pull, but to the reset.
-continue to do so until you have a short reset of your liking, I do not want to have a shorter reset than 1.8mm.
-stone true, and mirror polish the nose.
this is a trigger bar I did for my self defense G19 after Flexmoney point me VERY CORRECTLY (thanks flex!) on the possibility of short stroking my self defense gun after being accustomed to my competition G34 that has a very short reset.
My stock G19 has 4.4mm reset. Trigger pull 4.58lbs with 3.5 connector and 4lbs striker spring
With modified trigger bar it went 2.00mm reset with a trigger pull of 3.5lbs C-R-I-S-P.
So far I'm very satisfied. My competition g34 had a similar work done and it has 2.00 lbs trigger pull with 1.9mm reset, with Ti striker and a trapper striker spring (3lbs).
Hope it helps.
