I've got 2, one a standard steel wonderfinish, the other a match, both are in .45
they get used and enjoyed.
on the standard I put a adjustable LPA rear sight on it, and changed the trigger out to a single action. it shoots POA, and is confortable, no problems in over 1K rds either 230 ball or 185 JHP. I havent shot any 200 swc in it yet,
the trigger was changed only after getting the match, since I liked that one so well. no problems with the mags, & the mecgar mags.
The match has a tighter slide fit, and the only thing I've done to it is put a fiber optic front sight in it. I have about 500 rds through it, and when my wife goes to the range with me, she shoots it. I only had 1 problem with it, and I attribute it more to pilot error. the mag release is longer and if you bump it with your grip the mag drops out, and does not feed. it only happened once.
I did notice that the older one of the older witness mags I had does not want to lock in as well as the mag that came with it, or the mecgars..
so it is a little more finicky in that regard.
the trigger is a bit more smoother on the match, than the standard, with less travel. that's one of the reasons I changed it.
as far as what I think would be ideal, would be a standard in wonder finish with a single action trigger, dovetailed front sight, and adjustable rear sight.
also as far as the saftey, it seems a little more positive as far as locking the hammer from moving on the standards than on the matches.. you can put the saftey on and pull the trigger on the match and the hammer will move a little, not so on the standard.
while I see grumblings about poor customer service on the net, I haven't had to use any.
