Well…. We did it again… It took quite a bit of work... but we did it...
INTERDYNAMICS KG9 OPEN BOLT PISTOL, NEW IN BOX, UNFIRED AND IN ORIGINAL PACKAGING!
this one is for the serious collectors.
This is the extremely rare semi auto open bolt version of the Swedish Machine Pistol.
Designed by Interdynamic AB of Stockholm, the KG-9 was marketed and made in America as a blowback operated Open bolt pistol. It was so close to the original that it was found to be "Readily convertible to full auto"
Only 2500 were made before they were forced to cease production in 1982, and of those 2500, most were converted and registered as machine guns before the 1986 window closed.
Compare this production figure with the one hundred thousand plus RPB open bolt MAC pistols which were produced, and look at how rare the RPB guns have become and you will begin to understand exactly how hard to obtain this particular piece was...
Of the remaining semi auto KG9's many were illegally converted to Full Auto and subsequently confiscated and destroyed, so the number of surviving specimens of semi auto KG9’s Is extremely low.
Although this was determined to be a machine gun by the ATF, This one was made before Jan. 17 1982 and is considered "grandfathered" and legal to own.
This package is complete as it came from the factory; The gun comes with the original factory 36rd magazine (rebuild kit), the original cardboard shipping box in excellent condition, the original packing materials, the original twist ties which secure the gun into the cardboard and the original manual. The gun is in 100% perfect condition, with no wear what so ever. This is coming from the original owner who was a true collector and never fired this gun.
This is the only firearm which was ever produced which has the serial number engraved in the plastic of the lower receiver (not stamped in metal) and many of the originals were obliterated for criminal use using a small pocket knife and subsequently destroyed (further reducing the number in circulation).
This is a serious prize for a real collector. Only one or two KG9’s in any condition show up on the open market each year, and an unfired KG9 with all the original packaging is unbelievably rare
It may not be the only one of its kind … but if there are any others in this condition you could count them on one hand and probably would not need to use your thumb. This is an investment which will only appreciate over time.
Because of the extremely high collector value of this piece, it will not be altered in any way, we will be selling it in a disassembled state which will not harm the value. (upper and lower receivers will be separated prior to it entering CA, and the magazine will be disassembled and sold as a rebuild kit.... DO NOT ASSEMBLE IN ORIGINAL CONFIGURATION IN CA)
If you would like us to modify a Tec9 magazine to 10/30 condition (we won’t modify the original factory magazine…it is simply too valuable and the ghost of John Moses Browning would strike us down if we even thought about it) and provide a modified Tec9 magazine catch so that it can be assembled in CA, we are more than willing to do so for a nominal fee (so you can assemble this gun in CA legal configuration for display),
we really recommend that you do not fire this pistol as it may well be the only unfired KG9 still in existence…
This is sold as a unique collectible pistol, you are responsible for complying with all state and federal laws (i.e. don't do anything illegal with it, to it, around it. Don't think illegal thoughts, don't contemplate any hypothetical, don't ask any SHTF questions, and don't discuss anything nefarious even as a joke...)

ATF Ruling 82-3
The KG-9 pistol is a machinegun as defined in the National Firearms Act.
The Bureau of Alcohol, Tobacco and Firearms has examined a firearm identified as the KG-9 pistol. The KG-9 is a 9 millimeter caliber, semiautomatic firearm which is blowback operated and which fires from the open bolt position with the bolt incorporating a fixed firing pin. In addition, a component part of the weapon is a disconnector which prevents more than one shot being fired with a single function of the trigger.
The disconnector is designed in the KG-9 pistol in such a way that a simple modification to it, such as cutting, fitting, or grinding, allows the pistol to operate automatically. Thus, this simple modification to the disconnector together with the configuration of the above design features (blowback operation, firing from the open bolt position, and fixed firing pin) in the KG-9 permits the firearm to shoot automatically, more than one shot, without manual reloading, by a single function of the trigger. The above combination of design features as employed in the KG-9 is normally not found in the typical sporting firearm.
The National Firearms Act, 26 U.S.C. 5845(b), defines a machinegun to include any weapon which shoots, is designed to shoot, or can be readily restored to shoot, automatically more than one shot, without manual reloading, by a single function of the trigger.
The "shoots automatically" definition covers weapons that will function automatically. The "readily restorable" definition defines weapons which previously could shoot automatically but will not in their present condition. The "designed" definition includes those weapons which have not previously functioned as machineguns but possess design features which facilitate full automatic fire by simple modification or elimination of existing component parts.
Held: The KG-9 pistol is designed to shoot automatically more than one shot, without function of the trigger. Consequently, the KG-9 pistol is a machinegun as defined in section 5845(b) of the Act.
