If you are looking for a target pistol, the 745 is it. Don't know if you realize the 745 is a single action version of the 645. If you indeed want a target gun, a 745 would likely serve you better than the other models you mention. You don't say what the price of this gun is, and if the price were wishful thinking, I would pass too. If you can buy it for $450-475, it's a good buy.
