I'm looking to purchase a 642 and I saw the stock model with the two finger grip next to one with Crimson Trace grips that looked to be extended to three fingers. I didn't hold them because the store was mobbed. I want to be able to use it in a pocket holster like the Nemesis or Mika so I was wondering if any 642 owners have any insight into whether the extended grips will conceal well in a pocket.
