I stepped forward to buy a pistol or a revolver. I was going through an online search for the best one and there I came across an article in which detailing Arms made with 3d printers. I screwed my eyes into it deeply to understand how the 3d printer works and go through complete functions. This let me think of 3d printed guns, but there is some doubt that let me stop and think off. Firstly will the guns be stronger, safe, and trustworthy. Are these tested by masters for better usage?
