Got the idea from:
http://glock.pro/glock-pistols/2714-...eview-g19.html
Tools used: a pair of pilers, lighter, metal wire, sand paper, screw driver, a pocket knife.
(I do have better tools, but I was too lazy to go to the garage and get them. And they are too noisy for this time of the night.)
Materials: a stock magazine release, a small screw, a piece of black plastic that were cut from the case of a broken wall charger.
This is mostly made for experimenting... But it actually worked.
Now let the laughing begin.
