My wife carries a j-frame in her purse. It is in a zippered side pocket designed for this purpose. Her boss is a 'gun guy' and is ok with it in the office. After a casual conversation and her showing it to settle a debate on its caliber, he removed the round under the hammer and then said it was 'safer'. She now has a loose round and a four shot revolver. I'm a little perplexed. I don't want to make waves as he does allow it in the office and this keeps her from handling the gun daily just to go to work. My question is about the gun and its construction. Does the s&w 442 have some kind of hammer blocking device to prevent firing if the gun is dropped? Their website offers no clue. Anyone here carry their j-frame with an empty chamber?
