Glock18C: Metal Slide and Barrel Mod

This is my first time to disassemble and modify a Tokyo Marui Glock. At first I was kind of nervous or anxious but remembering how other people say that it's very easy, I went on with it.

Just like the 1911, the slide must be taken out of the frame first. The Tokyo Marui Glocks have the same field stripping process as the real Glocks. The slide lock must be pressed down first on both sides of the gun. Then, while holding down the slide lock, pull the slide back, and push it out front.

After that, the recoil spring guide assembly and the barrel assembly can be taken out from the slide.

The inner barrel assembly can now be taken out from the outer barrel.

The screw that joins the two halves of the chamber was undone to access the inner barrel and hop up rubber.

The PDI 6.01 Raven inner barrel and NineBall hop rubber replaced the original Tokyo Marui parts.

The inner barrel assembly was then put together again with the new parts installed.

Then it was oiled on the sides and inserted into the PGC metal outer barrel.

Now the slide was turned upside down and the screw that keeps the selector mechanism, blowback unit and the rear sight was undone.

The part that keeps the selector switch and mechanism in place was then taken out.

Also the selector block (I'm just making up the part names here depending on their function on the gun) and its spring.

Then the selector switch can be removed. This is a bit tricky to do so it's ok to take your time.

After that, the rear sight will just fall off on the other side. The blowback unit can be removed the same way in 1911s. The sides of the slide must be widened and with use of a finger the blowback unit can be pushed out from the slide.

Now the PGC metal slide was prepared by installing its small parts like the dummy extractor plug and the small circular part on the inner rear of the slide (I have no idea what they call it in real steel, I suppose it's an extractor pin. It's a dummy part in airsoft anyway).

The NineBall Tritium sight was screwed into the slide and the blowback unit and selector assembly parts were installed. Everything is just a virtual drop-in.

Now to finish the custom work, the new barrel assembly and the recoil spring guide assembly were put in place. (In the photo below, the recoil spring is still the original Tokyo Marui recoil spring).
