Tiêu đề Glock 19 Mag Extension - Plus 23 Tóm tắt Mở rộng băng đ

I made this Glock 19 magazine extension, it adds 2/3 in capacity.

The good

These can cost you about $40+ each, if you print them, well :) you only pay for electricity and filament, which isn't much.

The design prints just fine and it fits perfectly. You can even have a mag-well, and it will still work and lock in, no problem.

The bad

Not any material will work. I have tried ASA, and PTEG and these will break if you drop the mag from a 3ft when fully loaded. Now, I didn't try a 100% fill, which I might do that next.

I did print with a Nylon with Carbon Fiber, and this one did pass the 3ft drop test, meaning it did not break, but the mag did come apart. The reason for that, is the lip to hold it in place is slightly less than 1mm thick, and this is by the Glock team, not me. The reason it came apart is because, I think, my printer only prints one filament, and I did my bridge with the same nylon + carbon fiber material, and thus the bridge that is supposed to be holding with the magazine, was “rounded” instead of flat. This is because of the bridge support. My guess is, if I could print multi-material with my printer, maybe I could use a soluble filament and print a better bridge. If you can try that, and let me know if it does work or not.

I'm currently working on a different model that will break this part into two parts, and may be I can have a better bridge. In any case, I believe this model here will work if you can satisfy the following two conditions:

1. print with nylon and carbon fiber filament, which you will want a harden extruder for this, and at least a 0.60 mm nozzle, I printed mine with a 0.80 mm and some of the details get lost, but the part works fine.
2. print with multi-material and use a soluble filament as supports.

What you will need

besides the above requirements, you will need a few M3 hex screws, I suggest you get a pack like this:

but you only need an M3 6mm.

You will also need M3 Threaded Inserts, brass are good. Here is what I used:

you will need a soldering iron, what I did is, I placed the threaded inserts in the hole (they don't quite go in, but that was intentional) and then with the soldering iron, I heated the threaded inserts and put pressure to push them in, this worked fine, just be patient, it will take a little bit to heat up the brass and push it in. Once this is done, it will be solid in there.

Lastly, you will need a longer spring, the stock spring will not be long enough. I found some by Ghost Inc., they are much longer than you need them, but you can cut them to size. If you buy the pack of 2, you will pay just a little over $2 for each spring.

Notes

I don't get kickbacks from the links above, so feel free to shop anywhere you want. As a matter of fact, if you find better deals elsewhere, please let me know.

Make sure the print lines are parallel with the length of the magazine. This is because for extension will be a vertical force applied to it by the spring and the weight of the bullets. If the print lines are perpendicular to the length of the magazine, it will be more prone to delamination.

I don't consider this a final product, but that might be only because I'm missing the multifilament printing option, but I can't prove that it will work if you have that, so if you try it, and it works, please let me know.

Please connect with me and let me know how this goes for you.

It won't be long before 3D printers are the foremost recommended tool in households

Happy printing.
