Building your own gun isn’t difficult. In fact, it’s dead simple. At one time, I believed there was something mystical about building your own firearm. It seemed only someone with an engineering degree and years of training on a CNC machine could accomplish such a feat. Then I took the plunge and built my own AR-15 from an 80-percent lower that I machined in my garage.
The gun shot great, and I had broken through the mental barrier on what I could accomplish with some simple tools and a little effort. The next project that caught my eye was the Polymer80 PF940 incomplete pistol frame. Essentially a handgun equivalent to an 80-percent AR lower, the PF940 lets you build a full-sized pistol using Glock parts. It’s not exactly a Glock clone, as the shape, style and construction are significantly different. However, the slide, barrel, magazines and all other parts from Glock pistols work.
