I have been shooting my first model 52 for more decades than I can recall.
These are probably the finest shooting pistols ever produced by S&W. The triggers are fantastic and the groups are very tight. I have shot dozens of them over the years including the two I own
As mentioned the factory supplied magazines are 5 rounds. They can easily be altered to a 100% reliable 6 round capacity and some will even stretch to 7 rounds. I've got about 10 converted for 6 round use.
When the 952 was announced I was thrilled. A model 52 chambered in 9mm would be a GREAT gun. I bought one and went to the range with my 115JHP handloads that shoot a ragged hole out of my Walther P88. I was seriously dissapointed in the 952.
Do not get me wrong, the 952 is more accurate than S&Ws production 9MM pistols. It is a target gun in it's own right. It just is not a model 52 except in name and appearance.
The trigger was nowhere near a 52 trigger and the accuracy was not even close. My Walther would group tighter.
I tried four or five different factory loads, all of my hand loads and those the magazines of the day said worked best in it. None of them really thrilled me. I have fired several other folks 952s and found them underwhelming as well.
I admit that my expectations were probably too high considering the name 952. If they had called it the 39 Super Target or something like that I probably would have been happy with it. They just tried to fill shoes that were too big.
I kept my 952 because it is a beautiful piece and I hoped that one day I would stumble on a load that would make it group like it's namesake, the Model 52.
I am still waiting for that day.
The 845 would have been a better choice as the successor to the model 52. It does not look as good, but it performs as well as the 52s.
