Every Glock Part, Sorted

A Glock is two halves: the slide assembly on top and the frame with its fire control below. We have grouped the catalog the same way so you can jump to the part you are replacing.

01

Triggers & Lower Parts

Our signature Glock upgrade. The GRT Glock Reset Trigger is a one-piece stainless steel flat-face forced reset trigger for Gen 1 through Gen 4 Glocks and clones (not .22LR models) that installs on your existing trigger bar with a single roll pin. Shop connectors, springs and other frame parts alongside it.

Before You Order

Choosing the Right Glock Parts

Generation, model and caliber decide fit.

Know Your Generation

Gen 1 through Gen 5 Glocks differ in trigger housing, recoil spring, magazine catch and slide. The GRT fits Gen 1 to 4 and clones only. Every listing states which generations it fits.

Model Size

Full-size (G17, G22), compact (G19, G23) and subcompact (G26, G43) parts are not interchangeable across sizes. Sights and triggers often cross over; slides, barrels and magazines do not.

Caliber Conversions

A 9mm conversion barrel lets a .40 S&W Glock 22 or 23 run 9mm. You will also need 9mm magazines; the ejector and extractor usually work as-is but some builds benefit from a 9mm ejector.

Optic Cut

Optic-cut slides and RMR-cut Dagger slides use specific footprints. Match the plate or footprint to the red dot you plan to run.

Trigger Legality

Forced reset triggers and the Super Safety are semi-automatic fire control, but rules vary by state and change over time. NSPEC does not ship FRTs to CA, CO, CT, DE, FL, HI, IL, MD, MN, NJ, NV, NY, OR or RI. Confirm that any trigger is legal at your address before ordering and review the shipping restrictions.

Frequently Asked Questions

  • What is the GRT Glock Reset Trigger?

    The GRT is a one-piece, partially skeletonized, flat-face forced reset trigger machined from stainless steel. It fits Gen 1 through Gen 4 Glocks and Glock clones (not .22LR models), mounts to the factory trigger bar with a single 2x8 roll pin, and fires one round per pull with a faster mechanical reset. It sells for $44.99 with quantity pricing available.

  • Do your Glock parts fit Glock clones like the PSA Dagger?

    Many do. The PSA Dagger slide assemblies are Dagger-specific, while sights, magazines, barrels and the GRT are listed with the Glock models and generations they fit. Check the compatibility line on each product page.

  • What is the difference between standard and suppressor height sights?

    Suppressor height sights sit taller so you can see over a suppressor or co-witness with a slide-mounted red dot. Standard height sights are the factory profile. Both are available in tritium.

  • Can I convert my Glock 22 to 9mm?

    Yes. Install a 9mm conversion barrel and use 9mm Glock 17 magazines. Most G22 frames run 9mm reliably with the stock ejector and extractor.

  • Is a forced reset trigger legal in my state?

    Legality varies by state and changes over time. NSPEC will not ship FRTs to CA, CO, CT, DE, FL, HI, IL, MD, MN, NJ, NV, NY, OR or RI. Confirm legality at your address and review our shipping restrictions before ordering.

  • Do Glock parts require an FFL?

    Slides, barrels, triggers, sights and magazines ship directly to you with no FFL required. Shipments of barrels and high-capacity magazines to CA, WA, CT, NJ, New York City or Chicago require an FFL address. Complete frames are firearms and must ship to an FFL.
