Hello all. I need some opinions. I just got a used SP-01 tactical I have not shot yet. It needs a little work i.e. new guide rod, slide stop etc. I am planning on istalling a CGW pro package and any other needed parts and accessories, as well as having it milled for an optic and cerakoted. Should I upgrade/repair it first or have it milled first. Please let me know what you think. Thanks all.
Edit: Thank you all for your responses they have helped me solidify my plan for this one. I ordered the parts from CGW. I'm going to get it shooting stock, then send it to primary machine for the Harbinger milling package and have the frame re-finished at the same time. When it comes back I may keep it stock for a bit to use/test with the optic, last will be the pro package install. I'll post pics of the final transformation.
