COMPLETE SLIDE ASSEMBLIES FOR GLOCK 19®

COMPLETE SLIDE ASSEMBLIES FOR GLOCK 19® Reviews & Ratings

Complete, Fully Assembled Feature-Rich "Top Half" With Threaded & Ported Barrel Options


Top off your next custom pistol build or upgrade with our Complete RMR Slide Assembly for Glock® 19 Gen3, available in three configurations. You can get your slide with a premium match-quality barrel, a ½"-28 tpi threaded barrel to accept a sound suppressor, or with a ported barrel that vents through a window in the top of the slide to counteract muzzle rise and help you keep the sights on the target for subsequent shots. This eliminates the need to install a bulky compensator on the muzzle, which means your new comped pistol will still fit standard holsters for the Glock® 19.


These slides come fully assembled with the barrel and all the internal small parts installed, making this RMR Slide the ideal upgrade for your factory Glock® 19 Gen3 pistol or the perfect "top half" for a brand-new custom gun built on a compatible frame from another manufacturer. It features a pre-cut slot for easy, secure, low-profile mounting of a reflex red dot sight that fits the Trijicon RMR footprint. If you're not mounting a red dot at the moment, we've included a lightweight reinforced polymer cover plate to neatly fill the slot. Our RMR Slide comes with standard-height front and rear sights, which can serve as your primaries or a backup "iron" sights when paired with a red dot sight.

Each RMR Slide for Glock® starts life as a billet of 416 stainless steel that is machined to Glock® factory specifications inside, with a tough, extremely wear-resistant black Nitride finish. This slide fits standard Glock® factory G19 frames and compatible aftermarket frames. The match-quality barrel is machined from premium 416R stainless steel alloy. The muzzle of the threaded barrel has standard ½"-28 tpi threads. The ported barrel has eight ports angled to provide just the right counterforce to muzzle rise.


On the sides at the rear, you'll find distinctive wide, shallow cocking serrations that give excellent "purchase" to rack the slide, plus a mirrored set of serrations up front that aid in manipulating the slide to press-check the chamber. Both sets of serrations make it easy to manipulate your pistol's slide from any angle and in any position. We'll admit it: these serrations just look cool, too!

Whether you're assembling a custom pistol to meet specific needs, or you're upgrading a factory Glock 19 for enhanced performance and versatility, a Brownells complete slide assembly is helps you complete your project quickly and easily!

Does not cycle.
Slides have cycling issues with new design. Old design no issues. Numerous stove pipes, extraction and double feeds. I went through normal debugging. Changed ammo, parts including barrel, 1 at a time with no positive fix.

Horrible accuracy
First my credentials Im expert classified idpa shooter and a chief rso that helps zero dozens of pistol red dots a week and this by far is the most inaccurate upper ive ever shot. Absolutely no consistency one group 1 inch high next group 2inch low and left and the next 1 right all at 10 yards. Extremely disappointed

Way out of spec, massive safety liability
Ordered two ported and windowed slides. Sloppy fit, striker too high to mate properly with the trigger bar, can dry fire and leave trigger depressed, wiggle the gun and pin will send itself forward. Broke two trigger bars trying to adjust/increase height of the bar. Replaced Brownell's striker with OEM glock, still unsuitable sear-bar contact. Test fired them both, both have a tendancy to be more than semi-automatics in the most unreliable way possible. Pull the trigger, will you get one? Two? Seven? Reset the trigger, will you get any more? - probably. Dangerous and way out of spec, also likely to catch a felony charge. I returned them after attempting twice to reach out to Brownell's support and getting ghosted for a couple weeks. Quality control on the Brownell's slides seem to be slipping. They used to be quality slides, often a little too tight of tolerance. Now they are likely to get somone killed.

Limp Recoil Spring!
Recoil spring needs work. Very often the trigger failed to reset. It definitely needs to be heavier, closer to the OEM ones. On top of that, I also had issues with the extractor and had many double feeds. Both parts have been replaced and the firearm functions as intended. Overall, very disappointed.

Failed prior to first round
Guide rod failed and sent spring across room as soon as slide was attached to lower. Installed another guide rod and test fired successfully. Certainly not the quality product I expected
