With all of this talk about 3D printed guns lately, its sometimes forgotten that with a little know how, and a good set of hand tools can produce a working firearm. Being one of the most popular guns ever made, you can bet that the Glock has been reproduced a few times in garages and home workshops from time to time.
The mysterious Sawdust Glock
The Canadian website Impro Guns found an interesting Glock-style pistol. Unlike Gaston's masterpiece, which is striker-fired, this homemade gun uses a small concealed hammer. Instead of the proprietary blend of polymers, the gun uses a frame/lower receiver that is made of (among other things) compressed sawdust mixed with epoxy to form a particleboard resin. The slide was made from a solid block of steel and machined out just using a chisel, file, and a drill. Made in Russia where 9x19mm Parabellum is rare, it's chambered to fire the more common 9x18mm Makarov round.
Good luck passing a 100,000 round endurance test with this one. There have also been those who have made homebrew lowers from a piece of 4140 steel round stock which may last a little longer.
As a DIY project, Nick Westerbeck, a 16-year old student, made a mock-up Glock 17 style
pistol with the use of pine plank. Non-functional, the wooden gun still cycles its slide and would make a good training device for weapon's retention and practicing grip, stance, and draw.
In the small mountain markets along Pakistan's Northwest Frontier, and in many isolated islands of the Philippines there has for the past several centuries, been a burgeoning cottage industry in making firearms. These village gunsmiths, many of which were trained as apprentices under masters with generations of improvised gun making experience, can make virtually any type of small arms their customers ask for. As long as you have the gold, they can make you a knock off of any S&W, Beretta, Colt, Glock or any other such item if you have one they can reverse engineer. Some of these copies are so good they even will duplicate the markings and proofs.
Many of these guns wind up in the hands of terrorists, criminals, and rebels who could care less if the gun came from Austria or not-- so long as it works.
Here is a Vice Documentary about a backyard gun maker in the Philippines. While you don't see any Glocks-clones around, don't think that if you had a real one for them to look at and 2000 pesos, you couldn't get one.
After all, you just have 33-parts you need to make your own.
