I have a High Standard Double Nine W-100 .22 LR. My 21 year old daughter loves shooting it, but I was wondering about the safety of it. Specifically, does the hammer rest against the case and if it was dropped would it fire? I have always been partial to Ruger's transfer bar system and am considering buying her a Single Six. But if the Double Nine is not going to fire if dropped or if the hammer is struck, she would probably prefer it. Thanks
