Model 648 misfiring
My gunsmith said the strain screw was tight, but that the firing pin was too short. He ordered one from S&W & got an even shorter one back, says he has reordered & was told the next one will be long enough. Also said S&W was not surprised by the misfire issue. I have heard of Model 617's with same issue. Anyone else have an relevant info?
Thanks,
