Premium Aftermarket Glock Parts and Accessories for Glock G17, G19, G26, G43X, G48, and More Models

Glock parts and accessories are aftermarket and Original Equipment Manufacturer (OEM) components that modify, upgrade, or maintain Glock pistols across all generations and calibers. Glock accessories fall into 8 primary categories: triggers, sights, magazines, holsters, barrels, grips, lights and lasers, and slide components. Each Glock accessory serves a specific function - from reducing trigger pull weight to adding weapon-mounted illumination - and fits designated Glock models based on frame size and generation. TactaBlue stocks Glock parts and accessories for the G17, G19, G26, G43X, G48, G42, G43, G44, G45, and 30+ additional Glock models from brands including NDZ Performance, Ghost Inc., Magpul, Trijicon, Apex Tactical, and Lone Wolf Distributors.

Premium aftermarket Glock parts replace or upgrade factory components to change trigger feel, sight picture, grip texture, recoil characteristics, or muzzle device configuration. There are 6 primary upgrade categories for Glock pistols:

• Trigger connectors reduce pull weight from the factory 5.5 lb (2.5 kg) to as low as 3.0 lb (1.4 kg)
• Night sights and red dot optic mounts replace factory polymer sights with tritium or fiber optic aiming systems
• Threaded barrels allow compensator and suppressor attachment via 1/2x28 thread pitch for 9mm models
• Recoil spring assemblies tune cycling rate for specific ammunition loads or compensator setups
• Extended slide stop levers and magazine releases increase control surface area for faster manipulations
• Grip plugs, backplates, and slide cover plates seal the frame cavity and allow personalized engraving

Glock accessories are generation-specific. Gen 1-4 Glock frames share a pin configuration that differs from Gen 5 and Gen 6 frames. The G42, G43, G43X, and G48 use a Slimline frame that requires dedicated parts separate from full-size and compact Glock models.

Featured Products

NDZ Grip Plug for Glock 43X 48, Brass

The NDZ grip plug for the Glock 43X and G48 is a brass insert that seals the grip cavity behind the magazine well and adds 0.35 oz (10 g) of weight to the grip for improved balance. The grip plug prevents debris ingress into the firing control group and installs without tools.

NDZ Slide Racker Plate for Glock 43 43X 48, Textured

The NDZ slide racker plate replaces the factory rear slide cover plate on Glock 43, G43X, and G48 Slimline pistols. The textured surface provides a positive grip surface for one-handed slide manipulation, which is useful for press checks and malfunction clearance drills.

NDZ Decal Grip Vinyl Backing for ACS Grips 3/5", 4 Pack

NDZ decal grip vinyl backing measures 3/5 inch and comes in a 4-pack. The adhesive backing bonds directly to the Glock frame and provides a non-slip grip surface without permanent frame modification.

NDZ Aggressive Cut Series Decal Grip for Glock 17, 45 Gen 6 - Granulate

The NDZ Aggressive Cut Series decal grip fits the Glock 17 Gen 6 and G45 Gen 6 frames. The granulate texture pattern increases friction between hand and frame during recoil, which reduces shot-to-shot recovery time.

NDZ Aggressive Cut Series Decal Grip for Glock 19 Gen 6 - Granulate

The NDZ Aggressive Cut Series decal grip for the Glock 19 Gen 6 uses the same granulate texture as the G17/G45 version but is cut to match the compact G19 Gen 6 frame dimensions.

NDZ Slide Racker Plate for Glock Gen 1-5, Textured

The NDZ slide racker plate for Glock Gen 1-5 replaces the standard rear slide cover plate on all full-size and compact Glock frames from Gen 1 through Gen 5. The textured surface measures approximately 0.75 inches (19 mm) wide.

NDZ Slide Racker Plate for Glock Gen 6, Textured

The NDZ slide racker plate for Gen 6 is designed for the updated Gen 6 slide profile, which differs from Gen 1-5 in rear slide cover plate dimensions.

NDZ Pro Decal Grip for Glock 17, 45 Gen 6 - Granulate

The NDZ Pro decal grip for the G17 Gen 6 and G45 Gen 6 uses a pro-level granulate texture that covers a larger grip surface area than the Aggressive Cut Series.

NDZ Pro Decal Grip for Glock 19 Gen 6 - Granulate

The NDZ Pro decal grip for the G19 Gen 6 provides the same pro-level granulate coverage, scaled to the compact Gen 6 frame.

True Precision Glock Recoil Spring Tuning Kit for Compensators and Suppressors

The True Precision recoil spring tuning kit includes 3 spring weights that allow recoil spring assembly tuning for compensated or suppressed Glock pistols. Running a compensator or suppressor changes the gas pressure curve during cycling, and a lighter recoil spring compensates for the reduced slide velocity caused by the compensator's gas redirection.

True Precision Cobra Compensator, 1/2 x 28 Thread

The True Precision Cobra compensator threads onto any 1/2x28-threaded Glock barrel. The compensator redirects muzzle gas upward through 2 top ports, which reduces muzzle rise during rapid fire. The Cobra measures 1.1 inches (28 mm) in length and weighs 1.1 oz (31 g).

NDZ for Glock Gen 6 Optics Cut Cover Plate, Aspis Cut

The NDZ optics cut cover plate for Gen 6 fills the Aspis optic cut on Gen 6 Glock slides when no red dot sight is mounted, providing a clean slide profile and protecting the optic mounting surface from debris and holster wear.

NDZ Replacement Washer for Glock Gen 1-3 & 6, S&W SD9/40 Captured Guide Rod

The NDZ replacement washer fits captured guide rods for Glock Gen 1-3 and Gen 6 models, and Smith & Wesson SD9/SD40 pistols.

NDZ for Glock G43X, G48 Guide Rod Adapter

The NDZ guide rod adapter for the G43X and G48 allows installation of aftermarket captured guide rods on Slimline Glock frames.

NDZ for Glock G26 Guide Rod Adapter

The NDZ guide rod adapter for the G26 subcompact allows aftermarket captured guide rod installation on the subcompact frame.

ISMI Recoil Springs for Glock Full Size Models

ISMI recoil springs for full-size Glock models (G17, G22, G31, G34, G35, G37) are available in weight ratings from 11 lb to 22 lb, which allows spring rate tuning based on ammunition power factor and compensator configuration.

ISMI Recoil Springs for Glock Compact Models

ISMI recoil springs for compact Glock models (G19, G23, G32, G38) are available in the same weight range as the full-size springs, scaled to the compact recoil assembly length.

NDZ for Glock Laser Engraved Barrels, USA 250th Anniversary

NDZ laser-engraved barrels for Glock pistols feature a USA 250th Anniversary design and are available in multiple calibers and barrel lengths for full-size and compact Glock models.

Glock Accessories Compatibility

Glock accessories compatibility depends on 3 factors: frame size, generation, and caliber. Full-size 9mm Glock frames (G17, G34) share accessories with .40 S&W (G22, G35) and .357 SIG (G31) models of the same generation, because these calibers share the same frame dimensions. Compact 9mm frames (G19) share accessories with compact .40 S&W (G23) and .357 SIG (G32) models. The G42 (.380 ACP), G43, G43X, G43X MOS, G43X Rail, G48, G48 MOS, and G48 Rail form the Slimline family with dedicated accessories not interchangeable with full-size or compact models.
