Close to it, my cold weather daily carry is a S&W 686+, weighs the same as your 64 but holds 7 rounds of 357 Magmun flavor.
For some people the weight is objectionable, but it doesn't both me at all.
With a quality holster and the right clothing you should have no trouble carrying the 64.
At 5'4" and 125 pounds as long as my shirt is long enough I don't have any problems with hiding it, under the clothing I normally wear(jeans & sweatshirts).
If you like carry it, and remember a Smith & Wesson beats 4 aces anytime:smile:
