Gents:
I have an 80% g20 that I finished up recently. I ended up with a rock slide usa windowed upper, a lone wolf alphawolf barrel, a wolff recoil spring and guide rod, and basically stock upper/lower parts kits.
Originally I was having a problem where the round wouldn't fully seat when chambering, and it was because I accidentally ordered a 13lb recoil spring somehow. I replaced that with a 17lb also from wolff, however its still doing the same thing. When the slide comes forward to strip a round off the mag, it will get the round in the chamber and the slide will move forward until the last 1/4" of travel. Basically, the portion of movement where the barrel ramps up to lock into the upper receiver. It will stop at that last little bit, and you have to give it a small nudge with your thumb to get it to go "click". Its not gritty or difficult, it just acts like it has alllllmost enough juice but can't quote do it. It did this to me 20 out of 20 shots.
I know its an 80%, but the pistols seem hard to screw up and I really don't think its super likely that this was my fault in drilling incorrectly somehow. Does anyone have any ideas? Do I need to polish the barrel lugs, or change anything in their geometry? I would think not, and also since they affect the timing of the action I would prefer not to change anything. Is it possible that I need to run a 20lb recoil spring?
I know some barrels can run "tight" from what I have heard, I am not sure if the alphawolf has this problem. I am pretty sure it is supposed to be a "drop in" barrel.
