I shot my transitional 39-2 for a while last night, and got a few light primer strikes on double action on imported surplus ammo. I called S&W, asked for a new mainspring, and in about ten seconds, the girl on the other end says, "it's on the way. Anything else I can get you?"
I said, yes, I'm missing a 39 magazine spring. I bought a 3900 mag spring, and it doesn't fit the follower correctly.
"on the way."
I ask, "what do I owe you?" to which she replies,
"not a thing. Take care"
