MOD9V3 is a modular 9mm Luger semi-automatic 3D printed Pistol Caliber Carbine (PCC). Its defining differences from the MOD9V2 are the addition of an extractor to the bolt, ambi mag release, and ease of configuring and customizing the 3D printable files for the endusers build parts and choosen graphics, through the use of Openscad customizer. The MOD9V3 maintains the large compatibilty of build parts as the MOD9V2, except the bolt becaase of the more complex design. Supporting documentation for building the MOD9V3 is limited, but assembly is simlar to the MOD9V2, minus the portions relating to bolt assembly.
MOD9V2 is a modular 9mm Luger semi-automatic 3D printed and DIYable Pistol Caliber Carbine (PCC). Its defining differences from the MOD9V1 are the several internal improvements to the design and additional accesories in the months following the MOD9V1's release. MOD9V2 supports much more various parts to build with than the V1. MOD9V2 also has the most thorough supporting documentation of the firearms released by WF&GCI, and has its own dedicated assembly video series.
MOD9V1 is a modular 9mm Luger semi-automatic 3D printed and DIYable Pistol Caliber Carbine (PCC). MOD9V1's innovative design is a combination of part completely modular firearm, making it enduser configureable and built using various different parts, and part bolt over barrel design, from the WTF-9, making it a smooth shooting firearm incomparison to its peers. MOD9V1 is also the base design used for the MOD9V1 that takes M11 mags and uses ECM barrel, Wargoat,and MOD40. Supporting documentation exists for the MOD9V1, but it is limited by comparison to its successors.
WTF-9 series is a 9mm Luger, semi-automatic, partially 3D-printed and partially machined firearm. The WTF-9 is evolution of its predecessor, the AP-9 2020. It defining changes is the elmination of the buffertube bolt over barrel deisgn. The majority of the bolt weight over the barrel design has made the WTF-9 a more smooth shooting in comparison. WTF-9 series is also the base design used for the WTF-CA and WTF-9 AVZ. It is suceeded by the MOD9 series.
