Well, opinions are about like sphincters, everyones got one...
I, for one, am not thrilled with W&S 700s. Typically, this is a gun that uses a pair of hammers that have firing pins integral with same, and in the event of failure of the pin, you now have a single shot. Of course, a gun with a firing pin built separate from it's hammer can also suffer a firing pin failure, but, if the gun is equipped with disc set strikers, and you have the tool and a spare pin, you can easily repair it in the field. It is not easy or cheap to repair a hammer with integral strikers. I am told some 700s were built with disc set strikers, but, I have looked for years and never seen one.
I can think of a few other things to say, but, I'll start with this. You need to do some research. The more reading and study you can do before coming to a conclusion and parting with post tax dollars, the better off you are going to be.
Best of luck and do tell us how things work out.
Best,
Ted
