I have a new never-fired S&W 642 that I intend to give my eldest daughter (21) for Christmas, but dry-firing it I am concerned. The trigger doesn't trip the pin until it's only about 1/8 inch from the back of the trigger guard. It pinches and that just doesn't seem right. My 640 trips at a much more comfortable distance from the trigger guard. Is this normal? Will it change after it's been fired a few times? I shudder to think about her standing there with the thing pointed at the intruder and her flesh pinched behind the trigger and oops where's the bang... I'm very naive about handguns, she's even more. Young women should carry, don't you think? Thanks for any input.
