Obviously, the right answer is what she wants. If she wants to weigh our opinions, here is mine:
The LCR was a major breakthrough in lightweight pocket revolvers. My experience with several has been nothing other than flawless. They are light, carry well, and shoot very well for a gun that small and light. The stock grips are a big part of that and what they add to the size they more than make up for in boosting control and mitigating recoil. When you say that you will be installing a laser, what kind? I know that the crimson trace grips change out that beautiful stock grip and sadly, I don't have personal experience with them.
All my experience has been with the standard LCR models. Is there a reason she needs a hammer? Not having a hammer can go a long way towards comfortable carry and a smooth draw. Also, there are a few more options if you don't need the hammer. My favorite is the LCR 327. With .327 Federal Magnum, she'll get six shots instead of the standard five. Those shots will recoil like .38 +p despite having more power.
