Jammer's Twelve Step Program for Trigger Jobs:
Step one: Buy jigs. Lots of jigs. Consult the internet arm wavers, nay-sayers and whack jobs until you have one recomendation for every jig ever made, then buy one of each. Buy files, stones and lots of stuff. Tell your wife that it's like you're learning a new skill, and that these are tools. If your credit card has a low limit, less than a thousand dollars, be patient, and spend three months accumulating equipment.
Step two: File sear, file hammer. We all did it. You're no different.
Step three: Buy new sear, buy new hammer. We all did this, too. It how you learn the differences between the brands of hammers and sears. Buy one set of each brand. Shouldn't cost more than seven or eight hundred dollars. Soon, you'll be ready to buy the good stuff, but for now, use the cheap stuff.
Step four: Log onto the internet, wave arms, shriek for help. We're the internet generation, and have this huge advantage over the previous generation, who were known, for some obscure reason, as "The Pepsi Generation". Go figure.
Step five: Stone sear, stone hammer. Now you're getting somewhere. Your main objective with this step is to learn how to eliminate all engagement.
Step six: Buy new sear, buy new hammer, buy new jigs. By now, you will have Brownell's site bookmarked, and should be able to buy several jigs and half a dozen sets of sears and hammers in less than twenty minutes.
Step seven: Buy digital camera, learn to operate it, take pictures of ruined hammers and sears. Learn how to set up a web site, and post the pictures to your web site, showing step by step what you did, how you did it, and where it all went horribly wrong.
Step eight: Log back on, point to the pictures, describe problem, ("gun doesn't go boom", or "gun goes boomboomboomboomboomboomboom") shriek for help.
Step nine: stone sear, stone hammer, buy new sear, buy new hammer. You should be able to do this all in one step by now, and you should be able to ruin a hammer and a sear and order their replacements in less than fifteen minutes. At this point, the only delay in the process should be waiting for Brownell's to deliver a new hammer and sear.
Step ten: Throw jigs away. It's best to throw them through something that breaks, like a window or a Ming vase. A reasonable alternative is to buy a torch, melt them all down to a pool of slag, and blow holes in the hardened pool with a large caliber weapon. Someone else's weapon. Yours should be a box of parts in your safe by now.
Step eleven: Develop skill and touch by stoning old, ruined sets of sears and hammers.
Step twelve: Having had a spiritual awakening as a result of these steps, stone sears and hammers to perfect engagement, blindfolded, using your own, personal blend of karma, touch, skill, whispers of magic, The Force, and Far Sight.
There is no other way.
Have fun.
