Good advice guys, especially in the light of our current legal state in this country. My advice also would be to invest in some used guns that you personally are interested in, say, a S&W revolver that could stand a trigger job, or a used 1911 that needs some work, and stay up late studying the Kuhnhausen manuals on these guns, some AGI videos, the Wilson Combat videos on the 1911, and do some serious study and work on something. Preferrably ONE GUN AT A TIME. Nothing beats hands-on experience. Worke on your own stuff first - be safe for yourself before you dare to be safe for someone else.
Sometimes there are some experienced gunsmiths around who will let you ask questions and work with them for an hourly rate to learn also. Well worth it. I traded out favors and labor with a well-renowned gunsmith near my town years ago, and am very glad I was able to glean from his knowledge. He helped keep my butt out of trouble and out of serious mistakes too. Be warned -alot of these seasoned gunsmith guys are fairly "blunt" about their opinions, and will nail you down about why you want to learn. They don't want to waste time - it is precious to them. They have a right to be, so just say "yes sir" and jump in. If you get your feelings hurt easily, gunsmithing is not the business to be in.
One more thing: Please don't waste money on very expensive, fancy tools that are extremely specialized to start off with (in my case the SIG sight pusher, among other stuff!). It will help you go broke quickly. A good start in the business would be some polymer refinishing, cleaning guns for people before hunting seasons, and sighting-in and scope mounting are good starters too. Just my opinions. That's all. Good luck. Get an FFL, good insurance, and plenty of knowledge. And never stop learning.
