So... My new G19 Gen 4 trigger was not so hot. Sometimes there was NO take up - just a crisp letoff, however, long. Then sometimes after a warmup, it would have a long somewhat hard takeup, and a nice short crisp letoff. My son'e 2 nines (G19 Gen 3, and a G26 Gen 4) have PERFECT triggers. Nice light takeup, then crisp letoff. So, I thought I could smooth and lighten the take up with a .25 cent trigger job. I did the slide parts last week with a tad better takeup. Also 450 rounds helped a little, but I STILL had a 'variable trigger'. (Feels different depending on how you hold your mouth). So I did the connector and trigger cruciform yesterday. Now, there is a hitch in the takekup, it gets HARD, then a semi-mushy letoff. BAD. So... I guess I'll order an OEM trigger bar from Glockmeister and NOT try any more trigger jobs. With luck, this bar will be decent. (I'm 'unlucky' with triggers - if I pull a gun from a box, it WILL have 'variable' trigger.
