In an effort to increase the working lifetime of the FGC-9 Mk2's printed hammer, as well as significantly reduce the probability of accidental breakages, I have thickened the above-mentioned part to 12,4 mm.
I have also created two versions, one of which is solid, the other of which possesses an orifice for insertion of a 3x40mm screw (the extremity of the screw will, of course, have to be cut off).
The final printed product (with screw inserted) weighs over 7 grams, as opposed to the original, which weighed less than 4 grams.
Please note that this hammer is not backwards-compatible with the FGC-9's original bolt housing, and so a modified version of the housing with a 13mm-wide rear slot has been provided.
