I'm not sure if this custom firearm should be categorized under "neat" or "orama", but it's certainly unique.
It's a Glock model 21 .45 caliber pistol disguised as a DeWalt cordless drill, and it was created by Mark Bilicki with help from gunsmith James Oberkirsch. The drill element doesn't work, but the pistol is still deadly functional.
The question remains--what sort of person would want such a device? Maybe a disgruntled construction worker, or a hitman posing as a builder, or maybe Mark is both a gun collector and a big fan of DeWalt power tools?
