For prevention of accelerated wear, it is
highly recommended that the initial F&B be done on the steel parts only, before firing, and
then again after a few rounds when additional wear or rough
spots may become evident.
*1. Use a small piece of sandpaper
folded over for thickness and drag it through the rails in
both sides of the slide. The first few drags will remove some
finish and you can see the rough marks left by the milling
process. drag the paper through a few more time, you should
be able to feel how much smoother it pulls through. Be sure
to make contact between the paper and all three sides of the
channel before you are done. It is not necessary to
completely remove the mill marks, especially if they are
deep, you just want to make them smoother to glide across.
*2. Sand the hammer
interface using the sandpaper. Be sure to always finish your
polishing going in the direction of contact.
Sand to smooth the breech face. be careful not to damage the
Polish the inside of the opening that the barrel passes
through. Again go in the direction the parts move.
Use the sandpaper to gently dull the sharp edges on the slide
that will contact other parts.
Sand the flat areas inside the slide that contact the barrel
when the slide retracts. Don't try to remove the machine
marks, just smooth it a bit.
