Hello, all I have ended up with a Herter's .357, manufactured by Sauer & Sohn in 1966. Been doing alot of research on the gun and it seems to be mostly an oversized '73 SAA. Here's my problem: I know precisely squat about the SAA. My first single action revolver...I've had all kinds of pistols and rifles, and work on everything, but never messed with a single action. I noticed last night that when I cock the hammer all the way till it stops then let it go, she drops all the way to the firing position. Doesn't stop at the full cock notch, or the half cock. Now, if I cock it to full cock and slowly lower the hammer, like I normally do, is sets fine and dandy. Have notice that if I move the hammer to half cock and pull the trigger the hammer falls. I don't know much about it, but I'm assuming that the sear and hammer probably both have some issues. I've worked on my own stuff for years, built a couple of autoloaders, done a little trigger work, but I'm pretty new to revolvers, especially single actions. I believe I have found the parts, just wondering if anyone has any experience working on these-wondering if there is anything I need to be aware of before I dive into this project. Any experience anyone has out there would sure enough be appriciated... Thanks!
