Aint trying to knock Taurus customer service but I tried calling them on numerous occasions, I even left a message with my return info.......No luck.
My concern was not that my 22 magnum revolver was malfunctioning, but regarding the hammer spring. I understand that the 22 magnum case has an especially primer rim, so usually, a bit more hammer spring power is needed for reliable ignition as opposed to a 22 lr.
The hammer is so difficult to cock single action, that it leaves a blister on my son's finger after a session at the range. I'm far beyond 1000 shots fired, and I thought the spring would loosen up a bit, but it didn't. I thought that maybe they could offer me a hammer spring with a bit less psi. No luck.
I ended up removing the hammer spring, cut two coils off the spring, and ground the sharp point down flat. It's now much easier to pull back single action. Although still under brisk spring power, the trigger pulls at a full 18oz lighter. Should complement the over-travel screw I installed.
