Zeke, Tom Prince (aka Kivaari) is the one I plan on sending the trigger to. I've sent a couple emails back and forth and I think I'm going to send it next week.
About the sights, I looked into the tech sight, but I don't like the way it makes the gun look, that you probably have to permanently modify the receiver cover (which also makes disassembly more difficult), or the price. I'd like to keep the gun as stock-looking as possible so if I do change the sights, I'll probably get the Williams.
I've also considered the firing pin spring that was posted, but I don't think I'll do that right away.
About cleaning the firing pin. I disassembled the bolt and soaked all components in mineral spirits then cleaned the firing pin and channel with Hoppe's Bench Rest, and again in mineral spirits to rinse out the Hoppe's. The firing pin seems pretty free, but if I push it all the way forward forward it'll stick a little. If you just touch the front of it, it'll move back into the bolt, but it won't go back from shaking the bolt. Is this how the firing pin should be, or should I spend some more time trying to clean it? It's already soaked in mineral spirits for almost 48hrs.
