Glock 19 upgrade kit. Cap firing.

 

Important! Before you start. You must have experience printing and assembling complex models, such as this one https://makerworld.com/en/models/2700947-glock-g19-articulated-toy-optimized-version#profileId-2994240

If you have managed to assemble a fully working version, you can start this project.

 

This is an upgrade kit for a 3D-printed Glock 19. With this kit, your Glock 19 can fire 9mm printed toy ammunition. 

This model doesn't use real ammunition, only toy ones that work with caps.

 

There is a ammo: https://makerworld.com/en/models/2362620-9x19mm-para-functional-cap-firing#profileId-2585176

 

The barrel must be printed from a heat-resistant composite; ABS-GF has performed very well, withstanding over 100 shots. The barrel also needs to be cleaned with a plastic brush after every 10-15 shots and periodically with sandpaper. Since the cartridges use ring-type primers, the powder leaves a lot of residue.

 

For frame you can use any PLA

 

It's better to print the slide with a composite material. PLA-CF is quite sufficient. Regular PLA works well, but it has one weak point: due to the strong recoil spring, the slide stop lever wears down the part of the slide it engages with quite heavily.

 

 

Before first use, the barrel bore needs to be treated with sandpaper to remove the layer lines.

All mechanical parts that experience friction need to be lubricated. You can use silicone grease; WD-40 will also work =)

 

Requires:

Recoil spring -  Compression spring d-1,0 мм; D-10 мм; L-80 мм 

Firing pin spring - Compression spring d-0,7mm; D-7mm; L-45mm

Ejector pin spring -  Compression spring d-0.5mm; D-4mm; L-20mm

Sanding paper, needle files, Silicon grease.

 

!Warning!

The energy from a single cap is enough to fire a bullet that can pierce thick cardboard from several meters away. Yes, it is a toy, but it can be dangerous if mishandled. Do not shoot at people or animals, as this can lead to serious health consequences.

I worked on this project for quite a long time; all parts were redesigned and adjusted multiple times using different materials.
