Hello all. I plan to buy a new revolver for daily carry. I am 5'10" and175 lbs, clothing range from shorts and t-shirt in summer, t-shirt and jeans all year, suits to work, etc. Has anyone carried both the 340 pd and 442/642 that could tell me if it's worth the extra $250 to save the 4 oz on the 340? How noticeable is the difference and does lighter weight make it much easier to carry? Both guns are lighter than my current sig p239.
