MDX Arms G17 Series ONE Build Kit without JIG PF940v2 Glock 17

These are called BUILDERS Kits and not called “Assemble Kit” for a reason. You will need to file/sand/polish p80 frames/parts in order to make it work. Esp. for the subcompact, almost 100% of the time you will have to modify the locking block. If you are not capable of doing this then DO not buy these kits.
