COMPLETE SLIDE ASSEMBLIES FOR GLOCK 17® Reviews & Ratings

Complete Upper Assembly for Upgrading Your Factory G17 or a Custom Build


Top off your next custom pistol build or upgrade with our Complete RMR Slide Assembly for Glock® 17 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® 17.



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® 17 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 G17 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. Hey, we have to admit these serrations just look very cool, too!
Whether you're assembling a custom pistol to meet specific needs, or you're upgrading a factory Glock 17 for enhanced performance and versatility, a Brownells complete slide assembly is helps you complete your project quickly and easily!

Funtional, but wears
Brand new this completed window slide with ported barrel looks great, it also shoots amazing so no false advertising for helping with muzzle rise. I will say the coating on mine didnt last one range trip with kess than 50p rounds of 115 grain 9mm blazer brass. The ports while funtional and look great wore the finish on my slide and barrel HEAVILY.

Lacking Accuracy
Looks great! But accuracy is not very good. The rifling doesn’t look very good at all. I may have to get a different barrel, which would pretty much negate the value of this slide assembly.

Nice slide but I had two malfunctions with it today
I own a Glock 17 Gen 3 and installed this slide so I could upgrade my gun with a Trijicon RMR Red Dot Sight. I went to the range today to zero the sight and put some rounds through the gun. My Glock was cleaned and lubricated and I only use genuine Glock mags. Ammo is new and I've had zero problems with ammo from the same lot. First "shot" had a mis-feed which I cleared and then proceeded to send about 30 more rounds before having a second mis-feed. After I cleared that i didn't have any additional problems. In total, I shot 70 rounds and had two mis-feeds. This is concerning as I've put well over 1000 rounds through this gun with the factory Glock slide without any issues. Only now am I having issues. To the Brownell's folks, can you help me here? Any suggestions on how to fix this? If it matters, I'm using the original Glock recoil spring assembly and not the one included with the Brownell's slide. Could the two recoil assemblies be different? They appear to be identical and the springs seem to be of the same stiffness (or close to it).

Having some issues trying to work it out.
I've had issues with the slide lock being overly sensitive. I look at it wrong and the slide slams forward. The undercut machining doesn't leave much for the slide lock button to grab. Doing a polymer 80 build. tried bending button inward more. Am aware of hand position while firing. Have had issues with locking back on empty mag. I'm going to try a lighter spring to see if it's needing more backward motion. dropping from stock spring to 15lb spring with stainless guide rod instead of OEM style. Other than the bottom edge being machined at an inward slant I like the combo. When not firing it locks on mag but during fire its had issues.
