HughP, I just bought two CS40's. As best I can figure they were made from 1999-2001. Their low popularity was apparently due to sharp recoil, which I find no worse than a 3 inch light weight 45. Both of mine are DA/SA. A little creep in the triggers, it's not a big deal. The only range I have had these on since I bought them last week is a 50 foot range and I can do a good job of filling up a pie plate size Shoot and See target. You can chunk a lot of ammo in a hurry and stay on target. It does have some snap, but it's not a snub nosed .357 either. As soon as my new holster gets here I will make it a carry gun. I called Midway and they have all kinds of part and supplies for it. They are back ordered on mags, but they get those from S&W anyway. Try it you'll like it!
