It's ok, even good, not great - Rival Arms Glock 19 Gen 3/4 Precision Threaded Drop-in Barrel

I had this review on a previous Rival Arms G19 gen 3-4 listing that is now no longer active, here is the review as well as an update:

I had originally bought an L2D Combat barrel. However, after months of waiting for optics planet to ship it (backordered), I decided to cancel my order and get this barrel instead. I have seen Rival arms around and they seemed like a reliable and versatile company. Out of the box it looked great, cool logo with a unique design on top, nice spiral fluting on the barrel, nice black color, and fantastic lockup (better than the OEM by a hair and zero wobble). However, after installing and racking the slide a bunch (not firing yet) I could notice the finish diminishing slightly where the slide contacts the barrel. After putting 150rds through it (not a single failure, even in the "break-in" period, ran perfectly) I noticed the finish was not holding up in the typical places. I would say the finish is either the same or slightly more durable than OEM barrels, but I was expecting something that would barely wear at all (like the L2D barrel). If I could order another barrel in the same $140 price range (not counting the L2D as the DLC-black is on backorder for the foreseeable future), I think I'd go with GGP or silencerco. Currently runs great and I'll be testing it with a compensator in the next few days when it get's here, but I'll definitely have to spend another $50-$80 for a cerakote job to combat the wear.

Small problem as well: the thread protector looks very cool, but CONSTANTLY gets loose. Even when I'm just practicing my holser-drawing, the protector gets backed-out (when shooting its 10x worse). Its not problem for me since I plan to run a compensator, but if you aren't: you'll definitely want another O-ring, a new protector, or just take it off.

Update:

Finish is really coming off as I approach 1500rds. Still hasn't had any malfunctions, even with various different ammo (115-124-147, steel and brass casings) and a Harrington Arms compensator on it. Lockup is still great, again it runs pretty phenomenally but it's getting pretty ugly (or "battle-worn").
