The Glock 17 (Gen 3) is a standard frame 9mm pistol that is standard issue for many law enforcement officers and military personnel all over the world due to its accuracy, reliability, low weight, and large magazine capacity. The G17 and compact 9mm G19 Glock models are by far the most popular among Glock enthusiasts and offer the most aftermarket components, upgrades, and accessories.

A competition version of the G17 is available as the G34 model and features a lighter trigger pull, 0.83" longer barrel and slide with a window cutout and extended distance between the sights. Aftermarket parts for the G34 model are also readily available.

A long slide version of the G17 is offered by Glock as the G17L model and uses a 1.54" longer slide and barrel. The G17L is much less common than the G17 and G24 models so while barrels can be found, slides typically need to be sourced second hand.

Top 5 Glock G17 Upgrades

If you are building a new Glock pistol from individual parts or completing a Polymer 80 Glock frame, the parts list above will produce a completely stock Glock Pistol. While this is more than good enough for almost any application, there is always room from improvement.

The five best and most affordable upgrades you can make to a standard Glock pistol are an extended slide and magazine releases, a lighter trigger connector, a set of night sights, and a trigger job. The extended slide release and magazine release are easier to engage with your thumb and thus make releasing the slide and dropping a magazine easier with a firm grip on the pistol. An upgraded trigger connector and some time spent polishing the safety plunger, trigger connector, firing pin, and trigger bar will make the trigger pull lighter and smoother. Finally, a set of night sights will improve target acquisition, especially in low light situations.

Glock G17 Sight Upgrades

The most important upgrade you can make to any Glock pistol is to replace the factory iron sights with something that offers better visibility and target acquisition. For concealed carry applications, we recommend low profile "big dot" sights but if you can work with larger sights, some high visibility night sights are what we recommend most. For the ultimate pistol sight upgrade, consider a red dot or RMR, but keep in mind that these are bulky and will require an RMR cut slide (see below).

Glock G17 Trigger Upgrades

The trigger is the next most important upgrade you can make to your Glock pistol by providing a smoother pull and cleaner break. While regular use and/or time spent polishing the trigger components will improve the factory trigger pull, aftermarket triggers offer immediate enhancements including a wider trigger body for better purchase, reduced pre-travel, overall travel, and trigger reset, a smoother uptake, and a crisp trigger break. For further improvement, look for a trigger kit that includes a lighter trigger connector, polished safety plunger, lighter striker spring, and a lighter striker. Finally, for a perfectly fine tuned trigger, look for an aftermarket trigger with adjustable pre-travel and over-travel.

*Note that the factory trigger and trigger bar are one assembly and removing the locking pin will destroy the factory trigger. We highly recommend replacing them as a complete assembly.

Glock G17 Slide Upgrades

Aftermarkert slides offer a range of improvements over the stock Glock components including an RMR cut for a red dot sight, deeper serations for a better grip and heat disiption, modifed ejection ports, reduced weight, match grade tolerances, and advanced coatings for improved durability and service life. A basic slide will be made of standard grade 416 stainless steel and feature an RMR cut. Advanced Glock slides are machined from extra strong, heat treated, aerospace grade 17-4 stainless steel, have an RMR cut with an included cover, are precision machined for improved performance, and coated for wear resistance.

Coatings and Finishes
Phosphate/Parkerize - A phospate coating is a cost effective way to protect metal from corrosion and wear.
Nitride/Melonite - The Nitriding process case hardens, strengthens, and improves the corrosion resistance of the surface.
PVD - Phisical Vapor Deposition applies a thin layer of titanium (or other hard metal) to the to surface of metal.
DLC - A PVD coating of carbon, titanium, and nitrogen that creates an extra hard Diamond Like Carbon (DLC) finish.

Tools Needed to Build and Service a Glock Pistol

Thanks to their simple design, Glock pistols are very easy assemble, disassemble, service, modify, and upgrade. For basic work, all you need as a set of brass punches and a bench block, although, we highly recommend a Glock armorers tool that includes a front sight screw wrench. While changing or adjusting the rear sights can be done with a brass punch, a proper sight installation tool is well worth the cost to do it right and prevent damage to the components. Finally, with extended use, the channel liner in the Glock slide will wear out and the only correct way to remove the old one and install a new one is by using a Glock channel liner tool.
