DataDriven

I recently held my friend's Stock 2 and really loved it. The only issue is that I had a harder time reaching the trigger blade on the double action because it was a bit too far forward for me. The question I have is whether there are replacement grips possible that make a stock 3 work with someone who has smaller hands like me. Also, just to confirm, is the stock 3 more or less impossible to make legal for Carry Optics since it is at 45oz limit? Thanks in advance, Derek.
