Brownells Introduces Gen4 Glock 19 and Glock 17 Slides (1)

About a year ago, we reported the release of Brownells slides for the Gen 3 Glock pistols. Recently the company has announced that now similar slides are available for the Gen 4 Glock 17 and Glock 19 pistols. Let’s watch the video showcasing these new products, then go through their specs.

As seen in the video, the new Gen 4 slides come in two basic options:

  • Brownells Gen 4 Glock Iron Sight Slide – basic slide with iron sight cuts
  • Brownells Glock Gen 4 RMR Cut Slide – slide with a Trijicon RMR red dot sight cut

Both options can also be ordered with a top port.

A distinctive feature of Brownells slides that was present on Gen 3 slides too, is the existence of front slide serrations that are cut all around the slide. Here is how Brownells describes the advantages of such front serrations:

Unlike Glock OEM slides, the Brownells Gen 4 Glock Iron Sight Slide is machined with wraparound serrations that comes over the top of the slide, providing more textured surface area that’ll grab the skin of a shooter’s palm and enable them to draw the slide rearward in a flash.

The Brownells slides for Glock pistols are machined out of 17-4 stainless steel and feature a black nitride finish/surface treatment of black matte color. These are stripped slides that are compatible with standard Gen 4 Glock slide components.

The MSRP of the standard slide is $199.99 and the version with the RMR cut will cost you $229.99. The prices are identical for both the Glock 19 and Glock 17 slides. I couldn’t find the porting option price or a separate listing of ported versions of these slides. Probably, they are not yet available. I think it would be cool to see the Gen 4 iteration of their extended Glock 19 slides that have a G17 slide length thanks to the extended dust cover portion.

    I know the Gen 3 versions wouldn't fit a lot of holsters since they weren't within the evelope of of OEM glock slide. Does anyone know if this has been fixed?

    Don't know why they don't just add an ambi slide stop notch and let you use it on a gen 5 while they're at it
