At bullseye competition 45s dominate.
A major reason, 1911s aside is simply that the .451" hole will cut more rings on the target than will a .358" hole.
If you're set on a revolver, then it's hard to do better than the 625.
If you can handle rapid fire, 5 shots in 10 seconds, that is.
I do prefer the older -3 625s for this.
Now using a 5" one for occasional open sight matches.
