The Best Aftermarket Glock Slides [2023]

Modifying Glock pistols has become the new American pastime. From trigger swaps to barrel comps, the plain Jane Glock is now subject to degrees of modifications it has never seen before. One area that has grown in popularity recently is the use of aftermarket Glock slide options. From blinged-out designs to those made of titanium, there is an aftermarket slide for everyone! Let’s take a look at some of the best on the market.

The Best Aftermarket Glock Slide Options

Agency Arms Syndicate Slide

First up, we have an offering form Agency Arms. The Syndicate slide includes a stripped S2 slide and a recoil spring. The slide comes with the company’s well-designed Agency Optic System. This optics system cut proves one of the most robust optic cuts available on the market. Some key features include a variety of optic adapter plates, modular rear sight placement, a wider variety of iron sights, and a very solid attachment system. These Agency slides come machine from billet 17-4 steel and coated in Diamond Like Carbon.

From blinged out designs to those made of titanium, there is an aftermarket slide for everyone. So I put together a list of Glock aftermarket slides from seven different companies that perform incredibly well.

Take a look at the entire list below. Let us know what else you’ve used and what you’ve liked/hated in the comment section.

Zev Technologies Z17 Omen

No list of anything in the Glock aftermarket world would be complete without including Zev. Zev has several slides available, but one I really like is the Z17 Omen. It is pure Zev in that it embodies an aggressive elegance without going over the top. The slide has well-placed serrations along the side and top to provide great grip during manipulations. Forward windows also reduce reciprocating weight, which in turn, reduces fatigue and allows for faster shot follow-up placement.

The slides are manufactured from a single billet of 17-4 stainless steel to tighter tolerances than factory slides for increased consistency in barrel lockup, improving accuracy. The Omen also utilizes ZEV’s patented optic cut, which provides more thread area for keeping your optic securely mounted to the slide.

ZEV Stripped Slide Features

• Machined from 17-4 stainless steel billet
• Lowered ejection port
• Match-grade, precision milled tolerances
• Improved accuracy
• DLC or PVD coatings, increased Rockwell hardness
• RMR adapter plate included
• MSRP: $525

Brownells RMR Cut Slide

The Brownells RMR Slide for Glock 19 Gen4 improves the shooter’s ability to operate the slide and aim accurately under harsh conditions. It features distinctive, wraparound front cocking serrations that aid in manipulating the slide to check the chamber or clear a jam. The slide has a built-in mount for the Trijicon RMR red dot sight and certain Holosun sights enabling shooters to get on target faster and more easily than they can with standard pistol sights. 

The slide can come with a “window” cutout on top between the front serrations that enhances airflow to keep the barrel cooler – ideal for hard-working action competition pistols. Plus, if you have an upgraded barrel with a contrasting finish or fluting, the window helps your gun stand out from the sea of matte black on the firing line.

Brownells RMR Cut Slide Features

• Fits Gen4 Glock 19 pistols and clones
• Machined from 17-4 stainless steel billet
• Window and solid top models
• Pr-cut Trijicon RMR red dot mounting slot

Lone Wolf Signature SS 20 Slide

A name synonymous with any Glock mod over the years is Lone Wolf. In many ways, they were the first well-known provider of aftermarket upgrades to our lovable grocery-getter Glock. One of the best-looking options in their slide lineup is their Signature series. Lone Wolf considers these slides to be their finest, most interesting, and most radical creations. 

Signature Series 20 was first built on a 34-length slide as a proof of concept, with an angled nose and open windows in the front of the slide. Lone Wolf liked it as a prototype so much that they decided to offer it as a regular product! It features a tapered nose, angled slide windows throughout, drastic weight reduction through scalloping cut-outs, and aggressive slide serrations for the best grip surface possible.

Granted, there are many upgrades you can make to your Glock 19. However, the one that makes the greatest visual impact is the slide.
