Hey all, I’ve just about completed a polymer 80 Glock 19 build.
**Update**
- resolved. I added oil, I racked the daylights out of it pointing down at a 45 degree angle, and then down towards the floor, and repeated several times. The hesitation and slide getting stuck stopped today no matter the angle. There is now a palpable burr at the forward lockup interface on the top of the barrel, and bits of the oxide finish (what I'm guessing is the blackened finish) were coming off and coloring the oil I added/wiped black. The slide and barrel just needed to interface and deform to match normal operation. Dropping the slide from slide lock also sped things up I believe. I've learned that a rough finish may not mean just burrs, sharp corners, or machine marks, but also the lapping/polishing left undone may make for a longer break in period with dramatic changes. Thanks for the advice to hold back, that turned out to be very correct.
--------old problem below------
When I point the pistol downward while racking / cycling the slide there is enough hesitation on the forward travel to delay going into battery. Resistance occurs mostly at the start of forward motion. I can see the barrel travel forward a little before resistance is felt. Racking slide with pistol held level is smooth with no hesitation.
I suspect I need to file the barrel part that rides on the locking lug. Thoughts ?
