Glock 19 Complete Slide Kit (5 Best for the Polymer 80)

If you have just finished building your Polymer 80 Compact frame it is now time to order your Glock 19 slide completion kit.

It is easy to get overwhelmed with all of the upper Glock slide assembly kits available to order online with die-hard fanboys committed to one brand and hating on others.

I have personally built 4 Polymer 80 builds including the sub-compact(g26), compact(g19), single stack(PF9SS), and PF940v2(g17).

In my quest to find the best slide to match my P80 frame I have tried a different aftermarket slide kit company on each build.

Read on to save yourself some money and ensure your first Glock complete upper kit is worth the money and working out of the box.

When the word Glock hits the ears of any firearm enthusiast they instantly think “Reliability, durability, performance, and customization.” The first three characteristics have been proven time and again, but the customization or adaption of a Glock may be new to some.

What makes Glock even better though, is the option of selecting the best components and pairing them with a Polymer 80 frame. All you need to do is decide on the best Glock 19 gen 3 complete slide kit for your build.
The Glock is one of the most produced pistols giving owners a ton of options when it comes to buying Glock slides.

Glock 19 Slide Kits – What’s in the box?

One of the benefits of trying to source parts for a Glock build is just how readily available they are and the number of suppliers that carry them.

g19 slide assembly kit

Before you go swiping that credit card and ordering a slide kit, there is 2 questions you need to ask before ordering:

  1. Does the slide kit actually include the slide and barrel or is the kit simply the recoil rods, springs, extractors and so on?
  2. Are you purchasing the correct kit for the correct Glock model? For example, is the kit compatible with the Gen 1 to Gen 3, or is it specific to the Gen 5 only.

The kit below is for the Glock 19 Gen 1-3 and you will notice does NOT come with a barrel or slide:

  • Guide Rod
  • Firing Pin
  • Spring
  • Firing Pin Spacer Sleeve
  • Channel Liner
  • Set of Spring Cups
  • Rear Plate
  • Extractor
  • Plunger
  • Plunger Spring
  • Spring Loaded Bearing
  • Extractor Depressor Plunger
  • Extractor Depressor Plunger Spring

Now the kit below is a more common Glock 19 Slide Kit that most people are looking to build onto a Polymer80 frame and can be found on the MDX Arms website.

These come with the slides and Glock 19 barrels:

  • MDX G19 LF COMBAT19 9mm Slide with RMR Cut (6-32 Screw Thread Pitch)
  • Polymer Front and Rear Sights
  • Complete Gen 3 Slide Parts Kit with Guide Rod
  • G19 Non-Threaded Barrel in Stainless Steel or Black Nitride
  • RMR Plate with screws

Let’s Review Some G19 Slide Kits

80-lower.com – Glock19 Compatible Pistol Build with Serrated Slide

Description

Chances are if you are considering a Glock 19 built onto a Polymer80 frame and you have done just an ounce of research, you would have ended up at 80-lower.com at some point.

This slide kit is designed specifically for the Polymer80 mid-size frame and has all the necessary components.

What’s included?

  • Rear Serration Slide
  • Barrel
  • OEM-spec slide parts kit
  • OEM-spec frame parts kit
  • OEM-spec Gen3 Spring and guide rod

Compatibility

Gen3 Glock 19

What’s cool about it?

The best features when it comes to this kit are easily the slide itself and the barrel. 

The rear serration slide has that classic Glock look about it but it also comes with added benefits:

  • Rear-cut slide serrations
  • Heat treated to 41-44 on the Rockwell C scale
  • Matte black nitride finish
  • OEM internal dimensions
  • OEM Glock compatible sight cuts

Is there really any point in highlighting just how exceptional Glock barrels are? No, the reputation speaks for itself.

What is cool, however, in this kit is the barrel options:

Option 1 – Black Nitride

Option 2 – Stainless Steel

Option 3 – Threaded Black Nitride with Thread Protector

Option 4 – Threaded Stainless Steel with Thread Protector

Areas to improve on?

A bit of bling would be nice. Ok, we know it is not for everybody, and the die-hard Glock fans will be happy with this kit but aren’t customization all about designing in a way that matches your character?

Rockeybrass.com – Polymer Glock 19 PF940C Completion Kit

Description

Another one-stop-shop that offers the complete kit to complete your Polymer80 Compact frame. Yet, there are a few added benefits when dealing with Rockey Brass that we will touch on later.

What’s included?

  • Frame Parts Kit
  • Glock 19 Rockey Precision CES Slide with RMR Cut (Cover plate included)
  • Rockey Precision Slide Parts Kit
  • Rockey Brass DLC Barrel
  • Polymer Sights

Compatibility

Slide is compatible with all Glock 19 Gen 1-3 models

Slide parts kit is compatible with all Glock 19 Gen 1-3 models

Barrel is compatible with Glock 19 Gen 1-4 models

What’s cool about it?

There are 2 stand out features about this Glock 19 slide kit from Rockey Brass that we really like.

  1. Customizable options

Rockey Brass gives you the option of combining different slide styles, barrel options and sights when putting together your kit. Granted prices may vary when choosing various options but that is understandable.

  1. The Barrel

The barrel is a drop in replacement Glock 19 barrel in 9mm, but what we like about it is these barrels are manufactured specifically for Rockey brass by a quality US manufacturer and are warranted to be free from defects.

Areas to improve on?

Polymer80 builds are becoming increasingly popular, especially with Glock components and that means the availability of parts is increasingly inconsistent.

As mentioned earlier the great thing about the Rockey Brass slide kit is the options to select from, but it does seem many of those options are always out of stock.

JSDsupply.com – Patmos Arms Judah 19

Description

Does anybody else get the impression that JSDsupply.com has the feeling of being one of those online stores that were started by a friend’s buddy because he was frustrated with how things were, and is now absolutely crushing it with great products and exceptional customer service? Cause we do!

What’s included?

  • Patmos Arms G19 Slide
  • Internal components
  • Match grade, nitride coated barrel

Compatibility

Although it does not mention it specifically on the JSDsupply.com website, the standard compatibility would be with the Glock 19 Gen 1-3, but we suggest confirming it before purchasing.

What’s cool about it?

It doesn’t take long to notice that JSDsupply.com is not a fan of paperwork and a big defender of the 2nd. This is great because it takes the hassle and admin out of purchasing from JSD as they don’t require background checks.

Areas to improve on?

JSDsupply.com is one of those sites that you love to support and want nothing but the best for them.

However, the product descriptions are a bit lacking and need to include some finer details. This could make it hard for the new guys to gun building to understand exactly what they are purchasing. An example would be the compatibility of the slide kits.

80pbuilder.com – AGENT-19 Complete Upper for Glock 19

Description

As you can probably tell from the name of the website, 80pBuilder.com is all about jacking up your Polymer80 build to the max, and they have some awesome products.

The AGENT-19 is a great kit because it provides you with an almost unlimited choice of components for your build, more on that later.

What’s included?

For simplicity’s sake, the AGENT-19 kit comes with the following:

  • Slide
  • Barrel
  • Sights
  • Upper Parts Kit
  • Guide Rod

There is more to it than that, however, as 80pbuilder.com gives you the option of selecting the slide, barrel, sights, upper parts kit, and/or guide rod as individual components. This means you can pick and choose which parts you want, as opposed to it all coming as one kit.

Compatibility

Glock 19 Gen 3 with installation options available

What’s cool about it?

Touching on it earlier, we mentioned the options available with each component, giving you the freedom to really customize your build and see how much each component costs makes the process a lot smoother and enjoyable.

Slide Options:

  • Black
  • Flat Dark Earth
  • OD Green
  • Sniper Grey
  • Burnt Bronze

Barrel Options (prices vary):

  • Gold
  • Black
  • Stainless
  • Threaded Gold
  • Threaded Black Nitride
  • Threaded Stainless

Areas to improve on?

This was a tough one because the way 80pbuilder.com is laid out makes it so simple to navigate and the product photos of complete uppers are simply badass. 

If we had to be real picky though, it would be convenient to get a full list of all the smaller components within the Upper Parts Kit.

MDXarms.com – MDX Arms G19 Combat19 with RMR Cut Build Kit

Description

MDX Arms is one of those small businesses that put a lot of attention and effort into their customer service and ensuring the products they have on offer are of the highest quality. Two great characteristics to know when you are looking into doing your first build.

The Combat19 with RMR cut Build Kit is everything you would need to build onto your Polymer80 platform.

What’s included?

  • MDX G19 LF Combat19 9mm Slide with RMR Cut (6-32 Screw Thread Pitch)
  • Polymer Front and Rear Sights
  • Complete Slide Parts Kit with Guide Rod (Channel Liner Installed)
  • G19 Non-Threaded Barrel in Stainless Steel or Black Nitride
  • Free RMR Plate with screws

Compatibility

With the Polymer80 PF940cv1/Strike80 Frames and the Glock 19 Gen 1-3.

What’s cool about it?

The coolest thing about the Combat19 kit has to be the convenience. It’s a simple case of purchasing the kit knowing you have all the components to complete your build.

MDX Arms have taken it one step further by offering some really stylish slide colors and barrel finishes. There is also an easy option to throw in a lower parts kit at checkout if you need one of those too.

Areas to improve on?

We struggled to find obvious areas to improve and decided to sift through the +70 positive reviews for some issues. The only real negative that came up was a few gripes with a stiff recoil spring and a loose threaded barrel cap during firing.

Final Thoughts

The Glock 19 slide and Polymer80 frame are becoming quite the duo, some have even dubbed them the next “Pineapple on a pizza!”. Ok, no one said that but you get the point.
