Talk to David at TGD, he's a python guy.
I have an old 6inch nickel that my father bought brand new in the 70's. Best trigger I ever pulled. I ended up with a 4inch stainless that got me through FBI firearms school after being told that using a python was cheating. Lol. I lucked up the other day and found a 6 inch stainless for 600 and couldn't let it get away but the trigger is nothing like my other 2. Can't decide if I should leave it alone or get it worked on. And no it wasn't stolen lol.
