I hear through the grapevine that S&W is going to drop the locks as soon as:
They bring back the barrel pin
They start Counter-Boring magnum-caliber revolvers again (My only real wish)
They re-catalog the 5" barrel for their K, L and N-frames
They reintroduce carbon-steel guns with the Bright Blue finish
They offer real Ivory factory stocks
They put the firing pin back on the hammer nose (where God intended it to be)
They stop relying on C&C machines and MIM and go back to polished, hand-fitted, forged steel parts that are as smooth as butter
