Most Glock builders end up across three or four product pages trying to confirm that the barrel they want fits the slide they picked. This configurator eliminates the guesswork. Every component listed is verified compatible — pick your slide, pick your barrel, pick your internals, and it ships together.

What you configure:

• Slide — multiple finish and cut options for Glock 23 Gen 3 in .40 S&W
• Barrel — standard, threaded, nitride, or other finishes in .40 caliber
• Internals — 3CR Tactical slide completion kit included or already selected
• Optional sights — standard or tall co-witness height

All components are pre-verified compatible with:

• Glock 23 Gen 1, Gen 2, Gen 3 OEM frames
• Polymer80 PF940C frames

Not compatible with: Gen 4 or Gen 5 frames. Confirm your generation before ordering.

Assembly required. Lube all contact surfaces before first use. 200-round break-in recommended before carry.
