I bought and sold mine. I use a 649-3 instead. A 640 in 357, if you want the extra power, can be had without pro package too. Used anyway. I prefer the original design. Just my preference. I like the original combat style rear sight. Note that for a lot less money you can have a trigger job done on any revolver by a gunsmith or yourself if you have the skill. I bought a 640-3 with a magnaport and trigger job already done to it for $400 2 years ago. I think that was a much better deal. Again JMO
Here is a pic with the magna port and added grips.
