G20, I can't get the slide to go on. I picked up a new G20 and I was having an issue where I could not get the slide back on no matter what I tried. I could get it almost all the way but it would not budge after a certain point. I took out and put the barrel back in, I was messing with the guide rod and nothing would help. After a little google-fu, I found that others have had a similar problem. I was able to get it on after fiddling with the trigger a bit. I got it back together and everything was fine, the gun disassembled and reassemble just fine but then it started again. I can work around it but something is not right. If I install the slide until it stops, I then have to move it slightly forward and reset the trigger (for lack of a better description) by getting my finger behind it and pushing it forward. I can then move the slide back a tiny bit further until I hear a click. I can now pull the trigger again and the slide goes back on. This is really weird, I have a pretty thorough understanding of how the gun works and all I can come up with is that the trigger bar is interfering in some way. Yet when I compare every last part/detail to my G19, I find everything is identical (other than size of course) and nothing looks wrong. Is this possibly related to the trigger bar dimple? I have found a few other instances where folks were experiencing the same issue but there is no clear reason I can find. This gun is brand new and unfired, other that the test rounds at the factory.
