Congratulations to your Wife on her new SAR B6C and may it serve her well!
I have the SAR K2P/CM9 G1, SAR B6/B6P, and K2-45. Great Pistols all!
I have thought about getting a B6C, but my favorite LGS doesn't seem able to keep them in stock for very long and isn't offering any deals on them.
I got lucky just getting the B6/B6P from them, but I did get that one at a very reasonable price.
My K2P was not reasonably priced, but I bought it anyways. Not sorry!
My K2-45 had to be special ordered.
