Cabot Guns has done something truly special by creating the first mechanical devices made from a meteorite with its new set of 1911 semi-automatic pistols.

The aptly named Big Bang pistol set was fashioned from a piece of the Gibeon meteorite that flew through space for around four billion years before settling on earth. The mirror pistol set (meaning it comes in left- and right-handed versions) was dreamt up after Cabot had used the ultra-rate material as grips for another 1911 pistol, which was a painstaking venture in itself.

A special team at Cabot Guns used X-rays, 3-D modeling, EDM wire cutting, electron-beam welding, and a ton of sweat to create the one-of-a-kind meteorite pistols. And that process only began after Cabot made a pair of stainless steel clones to make sure there were no gaps in the process.

While the springs, seals, barrels, hammer struts, pins, screws, and side rails are not fashioned from the Gibeon meteorite, everything else is, including the frames, slides, triggers, magazine release, and grips. The result is truly beautiful thanks to Cabot acid-etching the meteor finishes to bring out the natural Widmanstatten crystalline pattern of the Gibeon meteorite.

The purchase price for the first-ever meteorite firearm set is $4.5 million, which, if that price is achieved, will make the Big Bang pistol set the most expensive guns ever sold.
