This pistol was a real education for me to build. I had not built a weapon befor this. You will need files, sand paper, screwdrivers, chisels, stain, sealer, possibly a drill. But most of all, elbow grease. It is a simple kit, but with all good things, you must put effort into it. I had to file about 1/8th inch off the front sight to bring the pattern up on the target. I am more than pleased with this piece. There was about 10-13 hours work put into it. Well worth it.
