SLIDE COMPLETION KIT FOR GLOCK GEN 3

Shadow Systems Slide Completion Kit — Glock Gen 3, 9mm, G17/G19/G26/G34

So you’re building or upgrading a Gen 3 Glock 9mm slide and want a complete internal kit with upgraded materials rather than sourcing factory-spec parts individually. The Shadow Systems Slide Completion Kit for Glock Gen 3 delivers exactly that. 17-4 stainless steel firing pin. 4140 nitrided firing pin safety and extractor depressor plunger. Every spring, bearing, liner, and sleeve included. No firearms transfer required. Ships directly across the UK and Europe.

Shadow Systems builds complete Glock-pattern pistols from scratch — so when they produce a SLIDE COMPLETION KIT FOR GLOCK GEN 3, they know exactly which components matter most. First, the firing pin is machined from 17-4 stainless steel — the same alloy used in aerospace and precision firearms for its strength and corrosion resistance. Next, the firing pin safety and extractor depressor plunger are made from 4140 steel with nitride treatment — harder surface, better wear resistance than standard factory parts. Finally, everything arrives matched and ready to install in one package.

Does This SLIDE COMPLETION KIT FOR GLOCK GEN 3 Require Any Transfer Documentation?

No — internal slide parts kit, not a serialised component. So the Shadow Systems kit contains a firing pin, extractor, safety components, springs, and small parts — none of which are serialised firearm components under UK or European law. Therefore, it ships directly to you without RFD transfer or import documentation across the UK and Europe. However, your Glock slide and frame must already be legally owned in your country before installation.

What Glock Models Does This SLIDE COMPLETION KIT FOR GLOCK GEN 3 Fit?

Gen 3 only — G17, G19, G26, and G34. So this kit is specifically designed for small frame 9mm Glock Gen 3 slides. Also, Gen 4 and Gen 5 use different internal geometry — particularly the extractor and firing pin safety configurations. Therefore, confirm your Glock is Gen 3 specifically before ordering. Gen 4 owners need a different kit.

What Materials Make This SLIDE COMPLETION KIT FOR GLOCK GEN 3 Different From Factory?

Three specific material upgrades over standard factory spec. So the firing pin is 17-4 stainless steel — stronger and more corrosion resistant than standard factory specification. Also, the firing pin safety and extractor depressor plunger are 4140 nitrided steel — surface hardened for better wear resistance. Finally, the firing pin spring and firing pin safety spring are 302 stainless steel. Therefore, the four most wear-critical components in this kit are all upgraded beyond factory material specification.

What Exactly Is Included?

Eleven components covering every internal slide part. So the kit includes: 17-4 stainless steel firing pin; firing pin spring spacer; firing pin spring cups; 302 stainless firing pin spring; 4140 nitrided firing pin safety; 302 stainless firing pin safety spring; standard extractor; 4140 nitrided extractor depressor plunger; extractor depressor plunger spring; spring loaded bearing; and firing pin channel liner. Therefore, you do not need to source any additional small parts to complete the slide assembly.
