On my current wishlist is a 3" 66 or if they exist 686 or something of that nature. My question to everyone is, why are 3" revolvers so scarce in the s&w lineup? I see 2" and 4" but there are very few 3" in the range. Many people see to agree that a 3" s&w .357 is pretty close to perfect for certain uses, so why doesnt the s&w range reflect that percieved need?
