The Rival Arms V1 barrel is one of the easiest ways to squeeze more accuracy out of a Glock 43 or 43X. It swaps in for your factory barrel with no fitting or gunsmithing, so you can have it installed and back at the range in a few minutes. The 3.41-inch barrel is CNC-machined from 416R stainless steel, precision polished, and finished with a low-temperature vacuum PVD coating that stands up to wear and the elements.
This one carries the details that matter when you're chasing tighter groups. It runs a 1:10 twist with 6-groove rifling and a target-crowned muzzle, which protects the rifling right at the exit point and helps every round leave the bore the same way. That consistency is where the accuracy gains come from, especially when you pair it with quality ammo and solid fundamentals. The fluted exterior isn't just for looks either, it helps shed heat during longer sessions and trims a little weight off a carry-size pistol.
The inner bore gets Rival Arms' BORSLICK Boron Nitride DCD treatment, which cuts friction and pushes back against heat and carbon fouling. In plain terms, the bore stays cleaner longer and wipes out easier when you do get around to maintenance. Over a lot of rounds that adds up to smoother, more repeatable performance and less time at the cleaning bench.
Since it's a true drop-in, this barrel fits both the Glock 43 and the slightly longer-gripped 43X, making it a natural upgrade for a carry gun or a range plinker you shoot often. It keeps the non-threaded muzzle profile, so it stays low-key and holsters just like the factory setup. Everything is built and machined in the USA and backed by the Rival Arms warranty, which is a nice bit of reassurance on a part you're relying on.
Yes. This barrel is designed as a drop-in replacement for both the Glock 43 and the Glock 43X, since the two share the same slide and barrel dimensions. The 43X just has a longer grip frame, which doesn't affect barrel fit.
No gunsmithing is required. It's a true drop-in that swaps directly for your factory barrel using the same field-strip process. Most folks have it installed in a couple of minutes with no tools beyond taking the slide apart.
No, this is the non-threaded version with a standard target-crowned muzzle. If you want to run a suppressor or comp, Rival Arms offers a threaded V1 barrel for the 43/43X with 1/2-28 threads instead.
The BORSLICK Boron Nitride DCD treatment coats the inner bore to cut friction and resist heat and carbon buildup. The practical payoff is a bore that fouls less and cleans up faster, which helps keep performance consistent over long range sessions.
