Again it’s my opinion, yours may vary and that’s okay.
I am more comfortable and shoot better with my 929, my unloads and reloads are smoother, I can sight faster and hit better with the longer 6.5” barrel.
I also shoot production division and use the same load in my CZ and 929. (I was blessed with .355 chamber throats) That makes my reloading faster and cheaper. I only have the one press and don’t want to change it over to .38 all the time and when I do have to change over I’d rather load .357
627 is a excellent revolver also. If I could only have 1 firearm, it would be on the top of the list.
