This is my first time posting here after a year or so of enjoying the forum. I have a Smith 645 police trade-in that I really like (good looks, good double action trigger, built like a tank) but I have a problem with the single action trigger pull. The take-up on it feels like a country mile and only activates the hammer when the trigger hits the back of grip. Is this normal or abnormal and is there much work that could be done to improve it? I'd be glad to hear from any fans/users of this short lived model. Thanks~

Sounds like your 645 could use a gunsmith. Or better yet, a trip back to the wellspring: the S&W factory. I heard mostly excellent things about their service.
I have a 4506, and like yours, the SA take-up is long... although in my case it's feathery. The let-off is not that tight -- there is some over-travel. Email their service dept, see what they say.

No idea. They can tell you. But with your 645 being at least 22 years old, you also might want to invest in a full set of replacement springs. On a 1911, I'd say just buy Wolff springs and do it yourself, but a Smith 3rd Gen (or 2nd Generation, in your case) is a lot more complex. When you get a quote from S&W, post how much. Somebody else will need to know down the line...
I'll do that Boomer. I've also been having problems with the gun not properly chambering the first few rounds too. It looks like the magazines need new springs because the rounds lie almost horizontal to the base of the magazine.
Why did S&W stop producing this model?

The 645 evolved into the 4506 back around 1985-1986, along with all the other S&W 3-digit autos evolving into the Third Generation models: the 659 became 5906, the 669 became 6906, etc. There might be some internal differences between your 645 and my 4506, but the most obvious one is the grip. You have separate grip panels; I have a one-piece wrap-around.
If you check out S&W current catalogue, you'll see that most of their 3rd generation guns carried over to today EXCEPT the 4506 ... replaced by their 1911.
