SOLD. I have a complete, brand new, Ruger polymer 22/45 frame assembly for sale. It is the latest model with removable grips. This is not an FFL part and can be sold to someone from another state or mailed to you. $ 265.00, or possibly trade. It is complete...and includes the complete mainspring assembly. Just add any factory or aftermarket Mark 2, Mark 3 or 22/45 "upper" (receiver/barrel,bolt group) and you have a complete pistol. It has the added bonus of an aftermarket part installed that replaces the much hated magazine disconnect "feature" found in the Mark 3 (see top picture). This change allows the gun to works like all other 1911 based designs, and makes it much easier to disassemble and reassemble for cleaning etc. I'm including the factory parts (magazine disconnector spring, and magazine disconnector..see bottom picture) should you ever wish to "re-Californiate" it. Also included (not pictured) are 2 - 22/45 magazine baseplates. You can change any Mark 3 magazine to a 22/45 magazine by simply changing the baseplate. And 1 factory "safety" (internal lock) key. Photos: If you have any questions.....just let me know.
